I've added a simple edge-smoothing function to debug island's generator. It
doesn't handle all edge cases (pun intended), but the proof of concept is
sound. I just wish I could release this...
I've also added exception checks to region.cpp
I actually don't remember what the RoomData's lua references where for,
but I'm pretty srue it wasn't this. I'll figure something out when I've
had a sleep.
