Logitech G25 support

VDrift includes a tool used to change G25 modes. The tool can be found in VDrift/tools/G25manage. The tool requires libusb development headers to be installed (package libusb-dev on ubuntu intrepid, for example). Run make to compile the tool, then run:

sudo ./G25manage --nativemode

and

sudo ./G25manage --range 900

The wheel should now support the entire turning radius as well as the clutch pedal.
