Moved progress bar movement to update: function.  Added animate start to move targetStar to earned start. Added SKEmitter to test out how the new emitter stuff works.
Updated the gameoverscene to actually show some label nodes. Added new functions to determine if the game is over and to swap out the scene. New function to save the game stats (score and stars earned)
New level table view, level select button and current level properties. User can choose and load any valid level. Update level data with user scores now works. New functions to wait for the animates to finish before ending the game. This makes for a cleaner game. New home image and level 3.
