Updates to the Simulator

The entire back-end of our online hub motor simulator has been revamped to properly model the effects of motor winding inductance. Although negligible with the low pole count Crystalyte motors, the winding inductance has a significant effect on the performance of geared motors and high pole count direct drive hubs like Nine Continent series, so our simulator now gives a much more accurate portrayal of these. While we were at it, we characterized and added several new motors to the simulator, such as our new 2805 NC hub, the fast 20" eZee hub, as well as the BMC V2 and MAC geared motors.
