Switch Light States over to the "non-On" states.

[tlewis17]

From Discord (ThomDrei): I did notice that you don't query the switch data for the lights because you are using the LIGHT xxx ON simvars and thereby querying the whether the actual light is on. So if I flick a switch but don't have the power on, it would not change the state of the switch if I make that dependant on the state that the plugin reports. You should query the simvars without the " ON" appendix for the actual switch states.
