The quest for better spacing in trees is afoot!  At the moment, it looks
alright, but there's a large gap between chunks to assure that trees don't
be doofy mcgoofy's and go outside of the chunk boundaries.  The next thing
I'm going to do is put a check in the chunk so if things are outside of it,
it just won't make them.
Merge branch 'master' of https://github.com/schiem/roguelike

Merged and cleaned up.  And responsed to that snarky comment.
