TODO/Ideas:
- Filter by size
- Log at bottom
- Imaging time constraint in hours calc
- Move some or all of the filtering to menus in the column headers
- Just use UserRole or UserRole+1 for the non-display roles.
- Altitude graph has some replicated code with the scheduler
- Weird timezone stuff when setting kstars to a timezone that's not the system's timezone.
- Add a catalog name, and display it
