Tim Culverhouse a8879d79c6 msgstore: remove duplicate calls to store.update
Move and Delete commands perform a store.update() when their worker is
completed and also when the method is called. This patch removes the
call performed in the store.Move and store.Delete methods.

Tim Culverhouse 399854c103 statusline: show threading status if threading-enabled=true
Update statusline to display threading status at startup. Previously,
the threading status would only display from a :toggle-threads command.
Users who had the config option threading-enabled would not see the
status, as a result.

Moritz Poldrack d7feb56cbe fix panic on closing a tab
This change fixes a panic caused by the selected tab being out of sync
when selecting a new one in widgets.(*Aerc).SelectedTab(). This happens
if the tab is already removed from the list of tabs, but the selection
not yet being updated.
This was achieved by moving the tabs behind updating the selection.

Koni Marti aae46c7afd composer: remove header if empty
Remove a header when it is empty.

Commit a253e89bda ("compose: prevent sending empty address list
headers") tried to avoid sending empty headers; but instead of deleting
the header, the empty string value was just ignored.

Tim Culverhouse 635530b12d msglist: fix panic for index-out-of-range
I didn't save the stack trace, but msglist.Selected() can create a panic
for index out of range due to the math operations in the map. My stack
trace resulted in a [-9]. This patch reuses the msgstore.Selected()
method, which already has bounds checking.

Koni Marti 4d3156ddf1 aerc: fix panic when backend is unknown
A panic occurs when an unknown backend is used. This regression was
introduced by commit a34be9eb36 ("status: use contextual ui styleset
for statusline"). Before this commit, an error screen for the unknown
backend was displayed. The contextual ui requires an account-specific ui
config but when the backend throws an error in the constructor of the
account view, the call to aerc.SelectedAccountUiConfig() panics:

panic: runtime error: index out of range [0] with length 0 [recovered]

Tim Culverhouse 4240f1fbfd perf: reduce calls to GetUiConfig
GetUiConfig was being called many times, and came up as a high CPU user
in a cpuprofile. Every call would merge a UIConfig, which is a costly
operation. Ideally, we would only need to have a config for every
account X every directory. We also have a context for subjects. This
patch stores all FOLDER and ACCOUNT level configs and reuses those
merged objects. The SUBJECT contexts are not stored in favor of merging
on-the-go, with a TODO comment to deprecate that feature and implement a
better per-message styling option. I suspect this feature is not used
very much.

Before applying this patch with my setup, GetUiConfig is called 1159
times just to open aerc. After applying, this is reduced to 37.

Sergey Smirnykh 12e8217d1f commands: implement prompt completion
This patch implements :prompt completion.
The completion mechanism only provides completions when there is at least
one argument specified (prompt text).
The mechanism is based on other commands' completions and works as follows:

   1. Attempts to look up a command by the name specified in args[1].

   2.a On success it uses command.Complete.

   2.b Otherwise, if total arguments count is lesser or equals than 2
       (i.e. no command arguments specified), it attempts to complete
       the command's name.

Additional effort is made to preserve prompt text, which often contains
spaces and formatting.

An non-zero exit code from the execution of gpg during decryption would
prevent aerc from parsing the output of gpg. The output should always be
parsed. Gpg can exit with an error due to not being able to validate a
signature. Aerc handles this error with the UI, and therefore all output
should be parsed regardless of exit state of gpg. The parsing of stdout
will find the errors and report back to aerc properly.

Tim Culverhouse de24d2d590 config: fix setting of zero-value time.Duration config values
When using section.MapTo(struct) (go-ini), if the struct has a default
value for a time.Duration type, a zero-value in the config will not
overwrite the default. If the type is *time.Duration, it will be
overwritten properly. One consideration was to change all
time.Duration types to *time.Duration. This method was chosen for ease
of implementation.

For example, if you set dirlist-delay = 0s, the delay will be 200ms.
This can be observed by logging the value just after mapping the ui
section in config.go. A config value of 0.1ms will have a delay of
0.1ms.

Currently, aerc has 4 time.Duration config values:
1. DirlistDelay - default 200 ms
2. CompletionDelay - default 250 ms
3. CheckMail - default unset (0)
4. CheckMailTimeout - default 10 s

1, 2, and 4 have a non-zero default value and are subject to this bug.
Only 1 and 2 are fixed in this patch. Number 4 would not make sense to
have a 0 second timeout, therefore we can prevent the user from doing
this by keeping it as it is.

Another option could be to set these to 0 in config.go. The default
config (aerc.conf) has these keys in it with their default values.
Presumably, we don't need to set them again in config.go. If a user
deletes the config values out of aerc.conf, the UI will function but
with 0s delays.

Tim Culverhouse be2abb3d91 binds: Open msgs in default Postpone folder in edit-mode
Add a default keybind to open messages in the default Postpone folder
("Drafts") in edit-mode.

A frequent question on IRC is "how do I edit a draft?". When a user
selects a Draft and presses <Enter>, the intent is usually to edit that
draft. This commit makes this the default behaviour for the default
Postpone folder.

Tim Culverhouse e785409904 binds: add folder context for message list binds
Add option to specify folder-specific binds for message lists. The binds
are layered: any existing binds in [messages] are overwritten by a more
specific bind in say, [messages:folder=Drafts]. The order is currently:

[messages] < [messages:account=<account>] < [messages:folder=<folder>]

Tim Culverhouse 7aa71d334b imap: add option to cache headers
Add option to cache headers for imap accounts. Cache db is located at
$XDG_CACHE_DIR/aerc/{account name}. The cache is cleaned of stale
entries when aerc is first opened.

Two new account level configuration options are introduced:
* cache-headers (Default: false)
* cache-max-age (Default: 30 days (720 hours))

The change in worker/imap/open.go is to set the selected directory. This
is required to access the UIDVALIDITY field, which is used in
combination with the message ID to form the key for use in the cache db.
The key structure is: "header.{UIDVALIDITY}.{UID}"

Where reasonable, cache does not stop aerc from running. In general, if
there is an error in the cache, aerc should continue working as usual.
Errors are either displayed to the user or logged.

All messages are stored without flags, and when retrieved have the flags
set to SEEN. This is to prevent UI flashes. A new method to
FetchMessageFlags is introduced to update flags of cached headers. This
is done asynchronously, and the user will see their messages appear and
then any flags updated. The message will initially show as SEEN, but
will update to unread. I considered updating the cache with the
last-known flag state, however it seems prudent to spare the R/W cycle
and assume that - eventually - all messages will end up read, and if it
isn't the update will occur rather quickly.

Note that leveldb puts a lock on the database, preventing multiple
instances of aerc from accessing the cache at the same time.

Much of this work is based on previous efforts by Vladimír Magyar.

Koni Marti e1d8bc4d17 msgviewer: open http links from messages
Parse http links from a message and display them as completions in the
:open-link command.

Add the following binds to the [view] section in your binds.conf:
<C-l> = :open-link <space>

Parsing can be disabled in aerc.conf by setting parse-http-links to
false in the viewer section.

Thanks to Moritz for the help with the regular expression.

Tim Culverhouse 4753cfd3e3 visual-mode: deselect messages after performing command
In order to better align to vim functionality: deselect visual mode
selections after performing a command on the selection. This patch also
introduces a new command to allow for re-selecting (remarking) the
previous selection set so that commands can be chained together. The
deselection only applies to msg commands that *do not* move the message
from the store (those types of commands already deselect):
- read/unread
- flag/unflag
- modify-labels
- copy
- pipe

Previous usage to mark several messages as read and deselect all:
Vjjj:read<Enter>:unmark -a<Enter>

New usage, similar to vim:
Vjjj:read<Enter>

To chain a command together:
Vjjj:read<Enter>:remark<Enter>{next command}<Enter>
