Allow colored lamps to emit light at full intensity

[eastballz]

Currently, lamps that have their color set via circuit emit light at lower intensity than regular lamps (white or with a hard coded color). Circuited lamps are normally used as signals rather than light sources, so I understand the reasoning. However, it's a bit limiting not being able to have them emit light at full intensity. In my case, I'm set up "disco science" lights around my labs and the result is a bit underwhleming.

Proposed change: Add a toggle under the "Use Colors" lamp circuit menu to allow emitting light at full intensity.
