This fixes a substantial performance issue when scrolling emails with
long/complicated contents, where scrolling down a single line can take
something like hundreds of ms before the screen is updated to reflect
the scroll. It's really bad if the email has lots of columns, e.g. like
if it's an html email that was passed through a filter (w3m, etc) to
render it.
Using pprof, I found that the multiple calls to vterm.ScreenCell.Attrs()
in styleFromCell were really really expensive. This patch replaces them
with a single call.
Here's a before and after with a simple, but very manual test of opening
a large email with contents that went through a w3m filter and
continuously scrolling up and down over and over for ~30 seconds:

bf0f72a533 ("template: add exec and wrap") introduced wrap which
allowed to chain wrapText. It also changed the aerc-templates man page
to document wrap instead of wrapText. The templates weren't updated
then, so update now.
As of now we crash fairly often. The problem is that we didn't run the cleanup
routine of the ui in this case, leaving the pty in a bad state.
Instead, recover from a panic and at least try to run the ui deinit.
Some packagers overwrote the version we embed in aerc, we really don't want that.
Hence we force clear the variable at the beginning of the makefile.
If git is available and returns a useful info we now use that version instead
of the hardcoded version
* Get rid of open_darwin
It just lead to code duplication for a simple one string change.
Instead we query it during initialization
* Accept user provided arguments
"open" on MacOS accepts things like -A to use a specific application
Pass trough arguments the user provided in order to facilitate this
* Refactor the function to a struct
This makes it more convenient for the caller and avoids signatures like
lib.OpenFile(nil, u.String(), nil) which are fairly unreadable
Also update to the tcell v2 PaletteColor api, which should keep the chosen
theme of the user intact.
Note, that if $TRUECOLOR is defined and a truecolor given, aerc will now stop
clipping the value to one of the theme colors.
Generally this is desired behaviour though.
We frequently had issues with notmuch segfaulting and my guess is that this
was due to the garbage collection magic used in the module.
This changes to a fork that ripped the functionality out.
Prior to this commit, the composer was based on a map[string]string.
While this approach was very versatile, it lead to a constant encoding / decoding
of addresses and other headers.
This commit switches to a different model, where the composer is based on a header.
Commands which want to interact with it can simply set some defaults they would
like to have. Users can overwrite them however they like.
In order to get access to the functions generating / getting the msgid go-message
was upgraded.
We made a new type out of go-message/mail.Address without any real reason.
This suddenly made it necessary to convert from one to the other without actually
having any benefit whatsoever.
This commit gets rid of the additional type
