xinput control support

[spielvan]

@xerpi bro, maybe xinput support would be something interesting, since almost all 8bitdo retro receivers work with xinput, xbox controller, adapted from ps2 controller to xbox 360, usb pc controllers, so it would be something very good for the fakemote project, Another thing I thought of after installing fakemoote 0.5.1 was perhaps a pop up at the top indicating when it changed from remote nunchuk to classic controller and an external application that allows mapper play by game individually and that informs the version of fakemote installed. Big hug bro and we're always together.
