By using VID and PID of Valve's SteamController, Steam doesn't give us ANOTHER "fake" XInput device
Therefore it's not necessary anymore to count controllers before we plug in any virtual controllers
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
this significantly reduces input-lag while keeping cpu usage at a minimum
also removed any of the vsync / framerate options as we now always render the overlay with 60fps
this reduces cpu usage and unnecessary overhead if playing with the default option of vsync on high refresh rate displays
