 ******************************************************************************
 *                                Changes
 ******************************************************************************
 *
 *  Change 1:	2014-10-10 (wackford)
 *				Added setLevel event so subscriptions to the event will work
 *  Change 2:	2014-12-10 (jscgs350 using Sticks18's code and effort!)
 *				Modified parse section to properly identify bulb status in the app when manually turned on by a physical switch
 *  Change 3:	2014-12-12 (jscgs350, Sticks18's)
 *				Modified to ensure dimming was smoother, and added fix for dimming below 7
 *	Change 4:	2014-12-14 Part 1 (Sticks18)
 *				Modified to ignore unnecessary level change responses to prevent level skips
 *	Change 5:	2014-12-14 Part 2 (Sticks18, jscgs350)
 *				Modified to clean up trace&debug logging, added new code from @sticks18 for parsing "on/off" to determine if the bulb is manually turned on and immediately update the app
 *	Change 6:	2015-01-02	(Sticks18)
 *				Modified to allow dim rate in Preferences. Added ability to dim during On/Off commands and included this option in Preferences. Defaults are "Normal" and no dim for On/Off.
 *	Change 7:	2015-01-09	(tslagle13)
 *				dimOnOff is was boolean, and switched to enum. Properly update "rampOn" and "rampOff" when refreshed or a polled (dim transition for On/Off commands)
 *	Change 8:	2015-03-06	(Juan Risso)
 *				Slider range from 0..100
 *	Change 9:	2015-03-06	(Juan Risso)
 *				Setlevel -> value to integer (to prevent smartapp calling this function from not working).
