Added support for qgcRebootRequired Fact meta data value.

Move  MAV_PARAM_TYPE to  MAV_PARAM_EXT_TYPE as we're now using the proper MAVLink version.

Converted Structure Scan to use CameraCalc such that it now works with
camera specs.

Ignore Fact index if there are no enums (avoid adding an "Unknown" entry)
Add function to convert and clamp a (Fact) value.

Removed guess work from what parameters must be refreshed/updated when some other parameter changes. Added a "reset" flag that indicates when a certain parameter changes, the list must be reloaded.
Don't send a signal when setting a fact if the new value is the same.

Increase param ack timeout.
Retry when param set failed.

Remove debug output
Fact enumStrings and enumValues can not be changed independently. Therefore you only need one signal.

Handle initial storage
Handle image/video capture and storage.

Plumb through initial object mode on Vehicle

We have real meta data now. Fake meta data was buggy
