added support for saving data in the database. Added cf zone index to database. Now need to fix all exceptions

already reading DB. Problem: what do we do with the data? We should create the necessary crazyfly zones, in the exact position?

Fixed problem Moving markers. Still need to find out a way of moving the anti-zooming highlight circle
