Add a peek flag -p to the view commands to open the message viewer
without setting the "seen" flag. If the flag is set, it would ignore the
"auto-mark-read" config.
The SetSeen flag will be propagated in case the message viewer moves on
to other messages, i.e. with the delete or archive commands.

Add option to open a message in the message viewer without setting the
seen flag. Enables the message viewer to be used as a preview pane
without changing the message flags unintentionally. Before, the message
viewer would set the seen flag by default. The IMAP backend will now
always fetch the message body with the peek option enabled (same as we
fetch the headers).
An "auto-mark-read" option is added to the ui config which is set to
true by default. If set the false, the seen flag is not set by the
message viewer.

The worker uses a buffered channel to queue tasks. Buffered channels
are effective at FIFO, but are prone to blocking. The design of aerc is
such that the UI must always accept a response from the backends, and
the backends must always accept a request from the UI. By using buffered
channels for both of these communication channels, a deadlock will
occur.
Break the chain by using a doubly linked list (container/list from the
standard library) to queue tasks for the worker. Essentially, this is an
infinitely buffered channel - but more memory efficient as it can change
size dynamically.

When checking for an exKey, aerc inspects the key and the rune of the
event vs the exkey binding. Runes should only be inspected if the key is
a tcell.KeyRune. Some Ctrl-[:alpha:] keys report a rune in tcell, but
aerc does not have these bound to the keystroke definition. Only <C-x>
has a rune bound, and is one of the very few <C-> keys that can actually
be bound to exKey
Only compare the Rune field if the key is of type KeyRune. Otherwise,
compare the Key. Also compare any modifiers with the keystroke/key
event. These changes allow for any control or alt key combination to be
bound to the exkey.
Update documentaiton to reflect that the default keybind is ':', and not
<semicolon>

The maildir worker currently populates the list of mail folders by
listing all the filesystem subdirectories in the maildir directory.
Although there's no official specification for maildir subfolders,
they should all have cur/ new/ and tmp/ subdirectories to be valid.
This patch prevents directories that don't have those subdirectories
present on the filesystem from appearing in the account folder list.
This is useful for example to prevent ".notmuch" and ".notmuch/xapian"
from showing up in the folder list if using notmuch to index emails
while using aerc's maildir backend.

Add XOAUTH2 authentication support for IMAP and SMTP. Although XOAUTH2
is now deprecated in favor of OAuthBearer, it is the only way to connect
to Office365 since Basic Auth is now completely removed.
Since XOAUTH2 is very similar to OAuthBearer and uses the same
configuration parameters, this is basically a copy-paste of the existing
OAuthBearer code.
However, XOAUTH2 support was removed from go-sasl library, so this
change reimports the code that was removed from go-sasl and offers it
a new home in lib/xoauth2.go. Hopefully it shouldn't be too hard to
maintain, being less than 50 SLOC.

Instead of xdg-open (or open on MacOS), allow forcing a program to open

1) If :open has arguments, they will be used as command to open the
attachment. If the arguments contain the {} placeholder, the
temporary file will be substituted, otherwise the file path is added
at the end of the arguments.
2) If a command is specified in the [openers] section of aerc.conf for
the part MIME type, then it is used with the same rules of {}
substitution.
3) Finally, fallback to xdg-open/open with the file path as argument.

The exline widget works by matching actual keystrokes to a map of
keybinds, and if a match is found sending simulated keystrokes through
aerc. This has the effect of aerc thinking we are actually typing in the
expanded command, and aerc attempts to draw the completions. This
results in even basic navigation having two screen draws:
For example, pressing 'j' to select the next message (:next), draws once
for the initial key event and state change, and again after the
completion debounce timer.
Disable tab completion while aerc is simulating keystrokes. If the
exline still has focus after simulating keystrokes, restore tab
completion.

When an error is encountered fetching a header, the backends respond
with a type.Error worker message. On receipt of this message, the UI
deletes all pending headers. The headers are all requested again as they
remain on the screen, resulting in an infinite request loop - and an
infinite logging loop. The user only ever sees the spinner unless they
check the logs.
A previous commit intended to fix this, however it introduced a
regression where any message that was part of the fetch request would
also be marked as erroneous. This commit is reverted with commit
2aad2fea7d36 ("msgstore: revert 9fdc7acf5b48").

When cached headers are fetched, an action is posted back to the Worker
to immediately fetch the flags for the message from the server (we can't
know the flags state, therefore it's not cached). When scrolling, a lag
occurs when loading cached headers because the n+1 message has to wait
for the flag request to return before the cached headers are retrieved.
