aerc: Add mail type formatting

Mails get symbols in the flag column if they are sent by me, CC or BCC
me, or they are tagged as a 'list' (from a mailing list).

Added some additional info to status bar (current folder, recent and
unread counts), and extended the flag column slightly to accomodate more
flags.
