Commit: https://github.com/urho3d/Urho3D/commit/89f6b31a47f27f28814e115615f68026d475e0e2

Message: Enhance the ConvexCast function to take a start pos,rot & end pos,rot instead of just a ray, so that the swept shape can be rotated. Ignore collision to self during convex cast, if the supplied shape belongs to a RigidBody.
