I've hacked the trigger system to create a really basic teleport pad,
using the dirt tile as an indicator. This behaviour is not coded into the
engine, but is in fact scripted in lua.
This commit is messy, due to lack of sleep.
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.
