- fix some tiny bugs

- fix module system (sometimes the layout is broken due to falsly deactivated categories) - auth updates (setting permissions) - fix "category jumping" bug in acp - u_action is defined by the module itself git-svn-id: file:///svn/phpbb/trunk@5558 89ea8834-ac86-4346-8a33-228a782c2dd0
