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.

Must memset structures before use.

Changed (selected) mission item color to primaryButton instead of buttonHighlight
Adjusted some colors for better contrast
Removed a few JavaScript exceptions caused by the order of object destruction

Instead of hardcoded "QGroundContorl" strings

Some android versions leave a focus arrow indicator turd in the
control. This gets rid of it.
