Working moonspawn from tiled

Only 1 corner tile per tiledmap layer, else it gets all confused. Could
re-work it so that there's a way around this, but as I'm the only one
designing things for this atm I'll see if I can manage without. Updated
runMe.jar. Lots of hideous debug info on screen - please ignore.
Actually - someone make a boolean to use the "d" key to show all of
that. That'd be super. Smashing, Probably end up being me though.
