@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
- Added possibility to attach users to annotations
- Moved the legend to resize_bottom
- Hovering over the legend will highlight the corresponding annotation
- Some UI improvements
- User profile page shows the images associated with the user (not fully functional yet)
