Spiritus Astrum [P0-B10]: p1496: Towards Early Access

The next goal that I have been working on is the addition of several new enemy types for the third campaign of the game.

These are almost completely done. I have been able to mostly reuse code from other NPC and enemy types, but there are quite a few unique elements to these AI enemies too.

The basic logic works fine, and the movement, attacks, etc, all seem ok too.

I still have some debugging to do, but the AI mostly seems fine.
