Refactored scripts, added a smoother for Debug Islan

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

rsc/scripts/setup_server.lua
