@todo: user sidebar block displays 30 users maximum and only users with annotations associated with them, add a search field allowing to search for all other users
- Implemented user notification (I need testers for this since for some reason my server is not sending mails with PHPs mail-function so I couldn't test)
- Users can decide if they want to receive notifications by editing their profile
- Admin can decide if notifications is switched on by default for new users and users who have not saved this setting
- Guest user is now hidden when adding an annotation
- Added admin option allowing to convert a user annotation to a tag or note annotation when deleting a user
- Added admin option to remove orphaned annotations
- Fixed borders not showing when hovering over an annotation area when having borders switched off on photo hover
- Fixed issue on user page where sometime only one photo would be shown x-times
- Fixed pagination on user profile pages
- Implemented tag handling (tags can now be added while creating the face)
- When entering a tag the notes field is cleared and vice versa to avoid confusion
- Cancel confirmation dialog now uses jquery dialog
- Added helpers/photoannotation.php by tkott for XMP compatibility
- Fixed RTL positioning
- Fixed bug deleting annotations with the same tag
- Fixed annotation form positioning
