Prusa Mendel i2 plug and power switch (remix)

Power switch support remixed to hold combo plug switch and light from Amazon: [Amazon Link](http://www.amazon.com/URBEST%C2%AEInlet-Module-Switch-Socket-IEC320/dp/B00ME5YAPK). The switch hangs over a little bit, but it is just about as large as it could be before hitting the pulley or rail.
