- add additional auth check to the permission roles modules

- added new function to return globally used expressions (get_preg_expression($mode)). This should be very helpful in getting wide spread similar checks (regular expressions) to one place reducing the risk of forgetting to change every location if you fix one. ;) We will add additional ones later, at the moment only the email check is retrieved...
- added "active module" var to the module class returning the current active module
- changed call to image magick
- add administrator to global moderators group by default
- extend auth_option column a little bit
- other bugfixes
