Steam import

Just an Import of additional Rules made by contributors at https://github.com/ValveSoftware/steam-devices. For now the rule of "Zeroplus Technology Corporation P4 (hitbox)" will stay disabled, because I honestly couldnt find anything for this device, and onle https://fccid.io/2ADKM for the company behind. That's not trustworthy enough, nevertheless the rule is in (just disabled) for users who need it.
