 * fixedToCamrea now works for Groups as well :) You can fix a Group to the camera and it will influence its children.
 * Tilemap.createCollisionObjects will parse Tiled data for objectgroups and convert polyline instances into physics objects you can collide with in the world.
 * Loader can now load JSON files specifically (game.load.json) and they are parsed and stored in the Game.Cache. Retrieve with game.cache.getJSON(key).
+* TileSprites can now receive full Input events, dragging, etc and be positioned in-world and fixed to cameras.
