Added basic blocking (EnemyAI)

- changed var "player" to type "PlayerController"
- added Transform "playerTransform"
- all previous entries of "player" changed to "playerTransform"

- changed phase 1 setup to check if handleInterrupt passes
- handleInterrupt ()
- changed to bool (probably not needed)
- removed running assignment
- added check for playerAttack

- block ()
- added print statement for debugging
- random variable, will block only 50% of the time (currently)
- if blocking, sets movement to away from player (NOTE:  MUST BE CHANGED
TO DETECT PROPER SIDE OF AI)
- sets running frames to 2
- returns that it has blocked
