Fixed the lighting command RAMP TO ramp rate to always clamp within 0.1 and 100.0 to avoid endless rate of 0.0. (#1100)

Browse Source 
* Fixed the lighting command RAMP TO ramp rate to always clamp within 0.1 and 100.0 to avoid endless rate of 0.0.

* Fixed the use of default fade, ramp, or step when those optional parameters are missing from lighting command.
