Explicitly set jabber status should not be overridden

[kchen@mit.edu]

If I explicitly set a jabber status, it should not be overridden. (Alternatively, there should be a way to turn off auto-away. Actually, this is probably less confusing.)

I keep a backup jabber session (along with my backup zephyr session), and set my status to xa so that all messages will go (at least) to my primary session. However, after 5 minutes, I become away, rather than xa. Also, when I return to the session and use barnowl in any way, I become online again. I have to explicitly set xa again.
