First pass at AIM away messages. It is a little different from what most clients seem to do, in that an away reply is sent for each message received. Most clients only reply to the first one per away-session. Also, it's completely tied to the zaway functions, it should probably be separated out into aaway functions with a new "away" function that will get everything. Loop detection stuff should work and has been tested, but I'm not completely sure I did this right ... so odd behavior should be reported.
