When trying to search in less, keys bound to viewer functions can't be
used as part of the search query, which makes the search useless.
Add a view::passthrough binding mode and a :toggle-key-passthrough
command go toggle in and out of that mode. By default, typing '/' in the
viewer is bound to enabling key passthrough and automatically inserting
'/', to easily enter "less" search mode. When in the passthrough mode,
all bindings are ignored by default. The default binds.conf only defines
a single keybinding in that mode: <Esc> to get back out. $ex is bound to
<C-x> to allow typing colons.

aerc.SelectedAccount() is used in lots of places. Most of them without
checking the return value.
In some cases, the currently selected tab is not related to any account
(widget.Terminal for example). This can lead to unexpected crashes when
accessing account specific configuration.
When possible, return an error when no account is currently selected.
If no error can be returned, fallback to non-account specific
configuration.

pty.Getsize() is used in the Draw function of the terminal widget and wraps the
pty.GetsizeFull() function. However, pty.Getsize does not check the returned
error from pty.GetsizeFull before dereferencing the winsize struct. In case of
an error, this will cause a nil pointer deference and panic.
This has been reported in the upstream package, but in the meantime, we can

implements PGP/MIME encryption with go-pgpmail. The Encrypt() function of
go-pgpmail requires a list of public keys which are taken from the
keystore. The keystore is searched for the email addresses of all
recipients (to, cc, and bcc).
If you want to be able to read the encrypted email afterwards, add
yourself as a recipient in either to, cc, or bcc as well.
Public keys can be exported from gpg into aerc as follows:
$ gpg --export >> ~/.local/share/aerc/keyring.asc
When composing a message, the encryption is enabled with the
":encrypt" command. This sets a bool flag in the Composer struct.
A reapted application of this command will toggle the flag.
The encrypted message can also be signed by using the ":sign"
command before or after ":encrypt".

When using aerc for multiple accounts often bindings might differ
slightly between accounts. For example:
* Account A archives to one directory (:archive)
* Account B archives to monthly directories (:archive month)
Add account specific bindings to allow the user to add a "context" to a
binding group using a context specifier and a regular expression.
Currently the only context specifier is 'account'.
The regular expression is validated against the accounts loaded from
accounts.conf and the configuration fails to load if there are no
matches.
Contextual bindings are merged with global bindings, with contextual
bindings taking precedence, when that context is active.
Bindings are be configured using a generic pattern of
'view:context=regexp'. E.g.:
# Globally Applicable Archiving
[messages]
A = :read<Enter>:archive<Enter>
# Monthly Archiving for 'Mailbox' Account
[messages:account=Mailbox$]
A = :read<Enter>:archive month<Enter>
In the above example all accounts matching the regular expression will
archive in the monthly format - all others will use the global binding.

When using the notmuch backend, it often makes more sense to sort
folders (actual virtual folders, or queries) by the order specified in
the query-map file, rather than alphabetically. This patch introduces a
configuration option (disabled by default) that allows this.
Additionally, due to the notmuch backend previously using maps (which
are order-undefined) to store the list of queries, default query
selection on aerc startup fluctuated. This patch fixes that by using
slices to store query order.
Display threads in the message list. For now, only supported by the
notmuch backend and on IMAP when the server supports the THREAD

Setting threading-enable=true is global and will cause the message list

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:

Also update to the tcell v2 PaletteColor api, which should keep the chosen

Note, that if $TRUECOLOR is defined and a truecolor given, aerc will now stop

Generally this is desired behaviour though.
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.
Allow styles to be layered over a base style. The list of styles to
apply is layered over the base style in order, such that if the layer
does not differ from the base it is not used. The order that these
styles are applied in is, from first to last:
msglist_default
msglist_unread
msglist_read (exclusive with unread, so technically the same level)
msglist_flagged
msglist_deleted
msglist_marked
So, msglist_marked style dominates.
This fixes an issue where the msglist_deleted style was not being applied.
There is a window where a new dir entry isn't yet in the dirlist.dir.
dirlist.ensureScroll however expected to always find a valid index.
Add a check so that we don't try to scroll to a -1 index.
