Optimize scripts

The scripts need clean up and optimization regarding performance

  • Fix namespaces
  • Move KoensScripts to the correct locations
  • Rename MenuButtonHandler.cs to GameControls.cs and move all game start stop pause stuff there
  • isPointerOverUIObject in SampleSector.cs and CameraDragDrop.cs are duplicates -> move to separate helper class
