Mouse input sensitivity fix

Someone on reddit found a fix for the mouse input sensitivity.  apparently it's tied to the controller sensitivity in some way:

1. Set all your settings in 'Controller' ---> 'On Foot' to match all your settings in 'Mouse & Keyboard' ---> 'On Foot' for all the settings that can be made to be equal.

2. In 'Mouse & Keyboard' ---> 'On Foot', Turn off 'uniform soldier aiming' and 'zoom transition sensitivity smoothing'.

3. In 'Controller' ---> 'On Foot' set 'soldier aim assist' to '0' and 'soldier aim assist zoom snap' to '0'.

4. Also, in Controller' ---> 'On Foot', set 'aiming left/right acceleration' to '0', 'vertical aim ratio' to '100' and 'vertical zoom ratio' to '100'.

5. Still in Controller' ---> 'On Foot', double check the 'coefficient' setting matches the 'coefficient' setting under 'Mouse & Keyboard' ---> 'On Foot' (Not sure why he says that, because USA was disabled earlier, but do it anyway).
