Redone player collision by removing all refrences and usage of Bounds in PlayerCharacter.java. Added a new method PlayerCollisionPoint in Bounds.java mirroring PlayerBuildingCollisionPoint for other players instead of buildings. Added a new check in movement mirrioring the check for buildings but for players to ensure that PlayerCollisionPoint is called in each movement.
