[Suresh / Kiwamu]

 The MC REFL camera is now available. The camera name is "MCR" and you can call it from the videoswitch script.

(what we did)

 + repositioned and aligned the MCR camera.

 + checked the MCR camera.

  => found the camera view shows a negative image (i.e. the beam spot is dark and the background is bright !!)

 + replaced the camera by a spare one.

 + modified the videoswitch script because the input channel 3 was wrongly assigned to MCR.

  MCR was correctly assigned to the input channel 18.
