Megamouse 7b49249f5f Input: Add config lerp factor for buttons and triggers
Adds new lerp factors to the keyboard pad handler In order to simulate triggers and analog buttons.
See "Analog Button Lerp Factor" and "Trigger Lerp Factor" in the yml in InputConfigs/Keyboard/.
Values Range from 0-100 as before, where 100 is instant press and 0 is never.

Currently I'm not planning any GUI element for this.
