v4.2.0

CHANGED

- Removed the unnecessary pathfinding that Turrets had.
- Turrets now use the more general "enemy" flag instead of "Monster" type.
- Turrets now use a move() override that drops any self-driven movement.

FIXED

- Fixed turrets sliding across the floor when another mod told them to move somewhere. (fixed by the move() override)
- Fixed turrets not targeting Fungal Infection: Spore mobs. (fixed by the "enemy" flag change)
