Removed some messy old code. Added comments and things.

The txt file problem isn't worth the nasty work around. I'd think it's
best to just write a custom XML writer. The XML wrtier XNA has is very
strange, it dosn't work to well. The reader is fine. Will have to
manually edit level files still as there is lots of speical case mark up
needed for the XML reader. PHEWW.
