A little refactoring. This creates a basic test class (EditorTest) that builds a mock platform and controller. Most editor tests would like to extend this class.
Changing the way project json files are removed to ensure all json files are actually removed, even if they are not referenced in project assets any longer
Creating a test for the EditorIO.saveAll() method
Changing SaveGameTest so it also checks that EditorIO.saveAll does not remove files with extension different of .json (e.g. images)
