Massive number of bugfixes!

In addition to revamping enemy AI, I did a code review of all combat systems over the last week or so. I'm planning to implement a new difficulty in the coming weeks, so I wanted to go over things with a fine-toothed comb before then, and I found a lot of odd little things that weren't working quite how they were supposed to.

The update will probably come to patrons next week, with a free edition update to follow. The update will add the futanari encounter, a new quest, a new spell school, and a new mantra, in addition to the improvements and bugfixes coming to combat!
