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

Handle survey mode state

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

Adding some more logging

Allow plugin to validate parameter setting.

Don't allow "Take Photo" is status is not idle.
Handle In Progress response (basically, do nothing)
Request capture status when stopping video recording.

Instead of resetting all parameters when some parameter change, explicitly define list of parameters that must be requested when a given parameter change.

Retry requests for storage and capture info.

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.
