Arduino Teensy 3 compatibility

To be exact mchck can be compatibile with Teensy 3 which in turn is Arduino compatibile - https://www.pjrc.com/teensy/schematic.html

DFU loader fixes: http://hackaday.io/project/662-mcslck

All pin names are from teensy, so you will have to remap them to names on mchck board in your head!
