Progress on Implementing Dungeon Packs

Added code for parsing dungeon pack config files. The settings for our
built-in dungeons are now read from a file instead of being hardcoded.
One or two settings aren't being accessed yet and we still don't search
for other dungeon packs in the custom dungeon folder.  That'll come in
another commit.
Minor Change

Minor change - fixing spacing that was messed up by Eclipse.
