This needs Qt 5.9. Do not merge it yet.

* Stable_V3.2:
  Better handling a mission altitude default
  Change to fixed value is altitude when switching to Manual grid
  New coloring for child indicators
  Add new map indicator colors
  Correct hiding of heading on TAKEOFF command
  Home Position reset while in edit mode

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

Remove/comment off debug output pollution

Correct hiding of heading on TAKEOFF command

Remove debug output

Plan: Update home position when loading plan after vehicle already connected

Pulling mavlink with a reversal for the CAMERA_IMAGE_CAPTURED message. It's now back as it was so it won't break existing code.
The pull also brought changes to the GPS_RAW_INT message. Only MockLink uses. I entered zeros for all new fields.

Handle initial storage
Handle image/video capture and storage.
