xbox 360 wirelss receiver fix

A xbox 360 controller wireless receiver (http://support.xbox.com/en-US/xbox-on-other-devices/connections/xbox-360-wireless-gaming-receiver-windows)
Reports itself as "Xbox 360 Wireless Receiver" (typically) or "Microsoft Corp. Xbox 360 Wireless Adapter" (possibly) so it's detection should not contingent on finding "Microsoft" in the name string.
Also, its d-pad reports different button codes than a wired 360 controller so we need a new configuration for this pad.
