Fix loop bug. When selection a video as a projector (need to work on this metaphor) the loops are automatically set. Previous issues were due to id re-use.

Also, (almost) you can choose a light color value that a frame will be overlayed on with a Darken composite mode. This is almost working but is kludgey because the first frame is always coming up black. Will need to make adjustments in the light module.
