generalized cast_lightning so enemies can use it. They are pretty deadly now.
fixed annoying issue with the inventory automatically using the item at 'i' if you didn't just barely tap the key. Thanks Space Butler!
updated 'cast_fireball' so monsters can use it.  Ran into a weird issue where the splash damage was killing the monster before its turn was over. Then the game would crash trying to access 'monster.fighter' when it didn't exist.  Had to add several checks in Dungeoneer.py and the use_item routine in entities.py to check for this.
This is clunky, but works.
updated cast_confusion so monsters can confuse the player.  But it takes total control of the player and isn't as elegant as Crawl. It's hilarious though
tweaks to initial monster items
minor tweaks to entity starting items and updated README with some extra info.
