CSM Running lights "always on" need to be switchable

[rcflyinghokie]

Long running issue and graphics limit has had our CSM running lights always on regardless of power. This need to be made switchable/powered from the CM and of course the lights themselves toggleable like the LM docking lights.

The first step should be to remove the emissive material from the mesh. Then we can add BEACONs like the LM has. The lights themselves should be round meshes, but that's more of a want than a need.
