Physics2D tests (#129)

* Quaternion: Fix singularity on Z axis when converting to euler angles

* CollisionComponent2D: Add method to retrieve AABB

* Collider2D: Fix constructor for Box with Vector2

* Physics2D: Fix rotation (Chipmunk works with radian and Nazara degrees) and copy constructor of RigidBody2D

* Colider2D: Add New for convex and tests for the new classes
