Dive picture handling: Re enable multi select, improve mouse events

Some improvements for the dive picture tab and dive pictures in profile:
- Bugfix mouse event in profile: Only Left-click will open picture
- Bugfix mouse events in picture tab:
  - Re-enable context menu (Windows bug mainly)
  - Re-enable multi select in a nice way
  - Only double-left-click will open picture
