Drone connection process implemented
Drone refactoring + new functions + tests + project setup:
 - connection process improvements
 - change ARDRONE_SUPPORT  from 0x10 to 0x20
 - handing extra from Prestage to Stage to connect to Drone on Stage
 - drone brick Actions use act(...) instead of update(...)
 - added play led animation (updated native libs)
 - renamed TakeOff brick and corresponding XML's
 - fixed wrong naming of bricks
 - imported changes from native project->different led animations are now possible
 - all handle play buttons now direct the drone extras to the stage
 - applied coding standard to parrot sources
 - fixed style and code tests
 - Parrot sources catroid/src/com/parrot/* are not checked for license header
 - added missing translations
 - removed unused strings
 - DroneControlService calls optimized
 - stage activity droneConnection fixed
 - updated native libs
Project Setup
 - Added native libs to the catroid/libs-natives/gdx-natives-for-gradle.jar file.

Drone features added:
 - drone bricks added
 - new color for drone bricks
 - SettingsActivity refactored
 - drone preference string changed
Drone functions + standard project + tests + PreStage checks:
Functions:
 - StartDroneService only when drone is on the network
Standard project:
 - drone standard project
   (Note: only created when 'Pocket Code' folder is empty and using app with debug flag enabled)
 - new LED sprite for drone standard project
 - delete and recreate drone standard project on every startup
 - positioned sprites in one line on the bottom
Tests:
 - Prestage activity checks for drone connection
 - fixed source tests
Prestage checks:
 - control battery charge before going to stage
Drone demo project + bricks refactoring:
Demo project:
 - drone demo project
 - speed formular field for forward brick
Refactoring:
