OpenGarage_2.2

Building on top of a great product, this redesign expands on ease of connectivity and options of the board. It is slightly taller due to the fact that LCD connector needed to be fitted  onto the board. Additionally a voltage regulator had been added as option to the diodes used as voltage drop, ensuring more stable voltage for the controller but also to drive a relay.
Solder pads had been converted into 2mm JST connectors for easier wiring, expansion and mounting in general. Some of the pin signals had been routed through solder jumpers on back of the PCB for future expansion and compatibility with current firmware
