This time to handle correctly updating plan/fly view when plan changes

Update the user model to a single controller instead of multiple

Instead of hardcoded "QGroundContorl" strings

Use component id from heartbeat

Conflicts:
	src/MissionManager/GeoFenceController.cc

Includes ability to load params

Also change Plan Element selection ui

- GeoFence support comes from plugin
- Circle fence support
- Better param support
