remove 2 ui options. prefs window needs cleaning. the less the better. remember HIG/GNOME: LESS IS MORE. power users can use ACE (advanced conf eidtor) and we could use GOOD DESC there and nice strigs in DID YOU KNOW wiki so some stuff can be easier exposed

[mcsf] updated pt translation

new pot/po files

[gjc] add happy dialog to inform about tracebacks only if we have verbose on and user does not run from terminal or started X11 with startx

notify_on_all_muc_messages is set.

(prefs_del, prefs_put are not implemented yet)

False and roster is never shown
