Fix Multiple controllers / Cleanup

Browse Source 
By Unhooking Steams hook to XInputGetState, we can detect how many Controllers Steam "emulates", before pluggin in any virtual controllers.
This *should* enable the use of multiple Valve SteamControllers.

The unhooking procedure currently only works on AMD64 and prob. only with XInput1_4
