@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
- 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)

- 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
