my turn to break things... harharhar

- checking in permission settings and permission masks
- permission presets and documentation not finished yet
- added backtrace function to determine file/line for sql errors
- fixed marlist for orphan attachments/groups/logs/users
- able to change anonymous user settings/permissions now
- re-arranged admin permissions a bit (added some and removed some)
- setting forum permissions after creating/editing forum now selects every default group (copy permisson/dropdown to be added for adding forums)
- finished user permissions in users acp

note: the layout for permissions might change
devs: please empty the user_permissions in phpbb_users. Also, first change your auth_options table, remove all cache files and then re-set admin permissions. After having set the admin permissions you can update your modules table (else you will not see the permission tabs) - or empty the auth setting within the modules table to be able to see the permission modules (they rely on newly added permission options)
