Bart Janssens / Mbed 2 deprecated PS3_BlueUSB

Based on Peter Barrett\'s work on BlueUSB, I added support for the PS3 Sixaxis controller (both USB and Bluetooth). When connecting a Sixaxis via USB, it will be paired with the (hardcoded) MAC address of my Bluetooth dongle.

Dependencies:   mbed

Dependents:   PS3_BlueUSB_downstate
