CPU Opponent!

I've added the ability to play against cpu opponents with 3 different difficulties.

CPU Overview

The cpu is basically just a state machine with 5 different states for chasing, attacking, landing, recovering and ledge trapping. I plan to expand some of these in the future to allow the ai to handle more situations such as being on ledge, being in hitstun, dash dancing, shielding and more as situations come up. The different difficulties change the reaction time for different actions such as turning, attacking etc. Any feedback is appreciated a lot as usual and I'm looking forward to improving the ai's capabilities.
