Arsenic Electric Motors 1.9.1

• Added a lightweight 50KWh battery (saving 330 pounds or so)
• Updated all config performance info (well, minus power to weight ratio because brain don't work so good)
• Changed Arsenic E color to Orange Sanguine to distinguish it a bit more
• Updated all stock config thumbnails, and now the street-car variants have the plates display "RSNIC E" and "RSNIC X" to make them at least a little more distinguishable
• Changed the race config to use regular Arsenic motors because I felt the X variant was just too insane.

Hopefully this update fixes the complaint of the rear end going wonky while racing because I sure couldn't replicate it myself.
