I tried to make gajim more HCI friendly. ERRORS use Error dialog and not warning dialog. Need core implementation too. Also other fixes. plz see a comment for you yann (sre)

remove some ugly hack for autoconnection

PLEASE HAVE A LOOK. string module is deprecated. starting to change in order not to be deprecated. PLEASE HAVE A LOOK. I DID 2 times, maybe I missed sth though. split(' ') --> split() is the same so that's not an error [sep=' '] is the default one [and I don't expect that to change :P

I tried everything. In the end I did it the normal way. Focus works on message_textview. Yann have a look if you want to make the same thing in GC
