Update 2.2 Reworked AI

Update 2.2 Patchnotes:

I've reworked the AI of the easy and normal enemies.

Now its behavior is a lot more deterministic and should therefore be easier to predict by players.

They will now launch an attack chain with a fixed length and afterwards provide a fixed length opportunity window for the player to retaliate.

The Hard AI still uses the old system for a tougher and more dynamic fighting experience to give players who have mastered the core systems a new challenge.
