class higdialog class and add report this bug in exception dialog and add some fixes for adding icons to buttons

get_hostname_from_account(account_name) saves the day [yet another helper to make our lifes better :)]

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
