First draft of Loochi 0.6
 - Back to BLE112 module
 - New power connector layout
 - New switch layout
 - One diode to make sure that the programmers can not provide power to the led
 - Another diode to protect the linear power supply when Vout > Vin (see the datasheet)
One major fix (vias under the cpu removed) + minor adjustments

 * Removed all vias under the CPU
 * Fix holes for the lense
 * Fix size of power supply tab
 * Connect the button to the BLE Module
Routed connections + Added SPI on BLE connector + Some cleaning/Rework
Final changes before ordering the board (minor cosmetic changes)
