OLIMEX STM32-E407 modified to fit under the 10x10cm PCB size limit that is common with PCB batch services such as Itead Studio and Seeed Studios.

- Moved the 3 BOOT headers inwards
- Rotated the BOOT UART port 180 to allow better trace placement
- Moved traces around the BOOT headers away from the PCB edge
- Moved the resistors on the BOOT pins to allow for the new placement of the headers
Added gerbers to make getting the PCB made easy!
Added note to readme that the PCB has yet to be built/verified. Proceed with caution!
