Massive refactoring, bugfixes

• massive refactoring
• fixed bugs for movement logger
• fixed bug for Collider2dRenderer

Minor fixes

• added ability to set material color by MaterialPropertyBlock
• bug fixes
• minor improvements

Added visualizers for the most of 2D joints

• added gizmos AnchoredJoint2DVisualizer for DistanceJoint2D, FixedJoint2D, FrictionJoint2D, HingeJoint2D, SliderJoint2D, SpringJoint2D, WheelJoint2D
• added ability to track a position of EdgeCollider2D
• reworked architecture
• removed dependency for DebugDrawingExtenstion
• added ability to track a position of unmoved objects

Added Collider2dRenderer

New version supports visualizing through Collider2dRenderer which renders colliders shape to standard mesh. This version lacks most features of the gizmos-based visualizers but it works in standalone builds, can be batched in one draw call to minimize graphics overhead impact. You can automate routine operations for you visualizers with the new manager which can be found at "Tools/Physics2dVisualizer/Open Manager" menu.

Initial

Currently supports:

• Box2dVisualizer for BoxCollider2D (EdgeRadius not supported)
• Capsule2dVisualizer for CapsuleCollider2D
• Circle2dVisualizer for CircleCollider2D
• Edge2dVisualizer for EdgeCollider2D
• Polygon2dVisualizer for PolygonCollider2D (Multiple polygon Paths not supported)
• MovementLogger for tracking object's position and transform (Edgae collider not supported)
