coding styles in hawke commit: doesnt --> does not, nick --> nickname (Gajim user is grandma not hacker), spaces between operators, fixing one string (the rest I leave for the orignial author in 80 margin with python strings concentation)

* Use gettext for command help strings (hope I got this right!)
* Can now supply a message to be displayed to the other occupants when
you use the /part, /leave, or /close commands

Get information about self-contact from the right place, instead of just copying the current account status/priority

* Added help for all "/" commands (in groupchat)
* Added "/join" to commands

* Make tooltip behave if we're not yet connected when it appears, or if we're the only resource online.

name, not name stored in jid field.
Use the new get_jid_from_account in a few places.
