Internet available now has a signal

* Resume index adjust to previous coordinate command
* Takeoff always added to resume mission
* Remove camera id checks which are no longer part of spec
* Simplified de-dup logic

This way:
* GCS location is shown
* It follows same centering semantics of FlightMap
* Note: Vehicle is not shown

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.

Fixed inverse logic in camera parameter retry count
Skip close timeout if not Windows

Increase param ack timeout.
Retry when param set failed.

This needs Qt 5.9. Do not merge it yet.

* If new Survey is set to altitude fixed value then use mission default
altitude
* If the user applies a new altitude to the entire mission change
surveys to fixed altitude and apply altitude

This way if the user switches away from manual the altitude is preserved
