Title: Updated to allow RAMPS boards to use ultimaker style pannels

I updated the pins.h, configuration.h file and ultraLCD.h file to allow RAMPS 1.3 (and probably 1.4) boards to use an LCD (connected to AUX-4) and rotary encoder (connected to AUX-2). Optionally a momentary switch can be used to simulate SD card removal and reinsertion (Pin 31 AUX-4) by pulling the pin to ground.
