msn-style login
It would be useful if gajim had a msn-like login mode, for example if you're at a friend's house, it's a bit overkill adding a new account, and configuring, etc, just to see who's online or sending out a message. It would be nice if gajim could have a "quick-login" or something, that just asked you the jid and password, and when you log off, it doesn't save options, password and logs.
