Title: Adding support for UNL2003 Stepper Driver

This adds support for cheap stepper motors with UNL2003 drivers ( less than $5 US: DealExtreme ). I've added comments that give a good start for tuning, but it's not perfect. Also, I've added in a wiring diagram to get the drivers hooked up. (The code is probably not the best place to put the diagram and instructions, but oh well)
