(request) Guitar Support

[RyixDevelopment]

So i want to emulate games like GH3 and stuff on dolphin and i dont own a wii les paul or any other wii guitar and so im requesting if you could add support to bind controller or keyboard actions to said games. i mainly use a keyboard when playing games such as clone hero or yarg but i want to more easily play with family and friends and i would like to use said input method rather than normal controller
