Collision Detection for Player <--> Barrier

[Solution49]

Our Collision-Detections works absolutely fine, for smaller objects, because their collision-area, where pixels are getting proved is also small (ratio). But Barriers can be huge and their collision area too. So we need to create another Collision-Detetion for Barriers, to avoid huge performance looses.

Add another Collision-Detection Concept
in class CollisionMgr or by creating a new class
