#86 Remember status messages

[Anonymous]

It would be nice if Gabber would remember your status
messages, while switching back and forth between
different statuses.

For example,
If I am available, then set my self to away, I can set
my away message. Then, when I set myself back to
available, you get the default "Online" message. Same
with away, etc. It would be nice to have it remember
the last status message you had in each mode, and fill
that in by default on the status message window while
setting your mode.
