Add a plugin which handles the connection of a Sixaxis device, when a
new hidraw device is connected the plugin:
- Filters udev events, and select the Sixaxis device
- Sets LEDs to match the joystick system number (for USB and BT)
- Sets the Master bluetooth address in the Sixaxis (USB pairing)
- Adds the device to the database of the current default
adapter (BT association)
