New Light System added

Adding this cool light system, built off of my LightsOnAtNight script.
This lighting system lets you set the intensity, on, off, or have the
light come on at night. It also accepts API commands on channel -1234.
Command structure is simple. LIGHTS=bright or LIGHTS=auto. The script is
as simple as i could get it so other scripters can write control panels
for them :) happy scripting.
