Prevent the embarrassing forgotten attachment scenario by warning the
user before sending a message that may need an attachment but does not
have one. Whether a message needs an attachment is determined by testing
a configurable regex against the message body.

The MouseEvent method of the composer passes on the mouse event to it's
underlying grid while the composer is locked. The underlying grid then
passes on the mouse event to child objects of the grid, which are
referenced via fields of the composer (c.editor is a field in composer
but a child of c.grid, for example). When the grid attempts to pass on
the mouse event, it is referencing a pointer which is locked, and a
deadlock occurs due to the original lock in composer.MouseEvent.
Unlock before calling the grid.MouseEvent, and lock the composer again
after it is called.

Add check for public keys of all message recipients (to, cc, and bcc)
before sending the message. Adds an OnFocusLost callback to header
editors to facilitate a callback for checking keys whenever a new
recipient is added (OnChange results in too many keyring checks).
Once encryption is initially set, the callbacks are registered. If a
public key is not available for any recipient, encryption is turned off.
However, notably, the callbacks are still registered meaning as s soon
as the user removes the recipients with missing keys, encryption is
turned back on.

This commit adds gpg system integration. This is done through two new
packages: gpgbin, which handles the system calls and parsing; and gpg
which is mostly a copy of emersion/go-pgpmail with modifications to
interface with package gpgbin. gpg includes tests for many cases, and
by it's nature also tests package gpgbin. I separated these in case an
external dependency is ever used for the gpg sys-calls/parsing (IE we
mirror how go-pgpmail+openpgp currently are dependencies)
Two new config options are introduced:
* pgp-provider. If it is not explicitly set to "gpg", aerc will default to
it's internal pgp provider
* pgp-key-id: (Optionally) specify a key by short or long keyId

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".

Private keys can be exported from gpg into aerc as follows:
$ gpg --export-secret-keys >> ~/.local/share/aerc/keyring.asc
A message is signed with the ":sign" command. The sign command sets
