Rename camera modes for usability

Flight Speed changes were not flowing through rest of mission items

Resume mission fixes

* 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

Survey fixes

Android: Add debuggable to manifest

Split internet test into separate DNS lookup and connection.

Intrument Widget alternate control: Fix broken settings dialog display

Stable: Buffer overrun in UAS.cc

Offline map: Use FlightMap as base

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

Parameter force save and default disabled in non-advanced mode

Fixes: Mission linux libs, Console save to file

Better handling of resume mission upload failures

Internet availability test fixes

Mission upload: Extra paranoia around write index list

Mission/Survey related fixes

* 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
