* 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

* 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

Caused intersection failure in some cases

Moves all params into param array instead of using GeoCoordinate for
param 5/6/7

This gives drag clicks precedence over splitting.
