aerc 0.3.0

aerc 0.3.0 is the latest pre-release of aerc. Notable improvements in
this release include:

A new notmuch backend is available. See aerc-notmuch(5) for details.

Message templates now let you change the default reply and forwarded
message templates, as well as add new templates of your own. See
aerc-templates(7) for details.

Mouse input is now optionally available and has been rigged up
throughout the UI, set [ui]mouse-enabled=true in aerc.conf to enable.

:cc and :bcc commands are available in the message composer.

Users may now configure arbitrary message headers for editing in the
