Added temporary debug prints to copyfile
Fixed Empty Dungeon Guide Bug

Fixed the bug that caused "How_to_add_dungeons.txt" to be copied as an
empty file. The reason was very subtle. Also moved the file to a
different directory.
Updated Dungeon Guide

Updated the dungeon creation guide to refer to our new command names.
Corrected mistakes and improved structure of the guide. I didn't correct
some parts of it, but I'll come back to that later.
