FlxTilemap broken. Needs to adapt to the new API.

You need to clone or fork libgdx and hook the flixel projects to it.
Splashscreen added. Just do showSplashScreen = true in the game. Doesn't
work with screen resolution smaller than 480 x 800 px. Needs to fix this
with FileResolver.
FlxTilemap, rendering and tile flipping or correctly, but the order is not.
Fixed FlxTilemap with the new TiledMap API
Fixed y-up in FlxTilemap, should work now with the future release of libgdx.
Resolution file resolver added in FlxAssetManager

But it doesn't work correctly with Atlas!
