Trim damage types file. Manaburn will return!

Some of the other stuff I liked, just in case I forget I still have them in the repository's history here, included complicated drain-all-resources mechanics, projectile slowing, and paralysis.
Trim timed effects file - well, trimmed, but not polished.

Ideas which could return: Empower magic, gazes with blanket slow and -stun res, beholder bersker frenzy, paralysis with an in/out of gaze toggle.
