Auto switchable Turbo touch key based on FPS limit toggle

I hope this makes everyone happy as last commit reverts the turbo touch key back to its original behaviour and thus cannot limit to desired FPS let say 90, 120 etc or unthrottle (3 stages)

Right now when FPS limit enabled , the turbo touch key will change itself to the 3 stages and i think it makes more sense . If FPS limit disabled , it revert to its original behaviour .
