Implement Raycaster for many moving objects

[gonzalesMK]

I wish the following features on the Raycaster sensor:

1. Handle more than one item on mesh_prim_paths
2. Handle regex string on mesh_prim_paths
3. Handle moving objects (but not deformable nor articulated) on mesh_prim_paths

I'm interested in working on that if it is ok.
