Dungeon Fixes

Hey, really have no idea what I'm doing here... my first time using Github too. I tried to follow your idea of using a fork/clone/pull request.

How do you want to handle new releases? We shouldn't push a new exe without testing :) I don't trust myself!

A few dungeon bugs fixed here, and tried to optimize out some repeat loops that annoyed me. I'm working with local knowledge here (not familiar with whole codebase) so not sure how the monster loading works, or why he used -1 for the first monster and -4 for the others.

Thanks,
Dan
