Separate WASD and mouse movement

This feedback is about playing the game with mouse and/or keyboard. As it is right now when you play with mouse and keyboard the movement controls are a mix of both mouse AND keyboard. Even if you want to play with WASD controls there is no way to disable mouse movement which actually causes some issues.
This is because when you sprint (Shift) with WASD controls it works just fine as long as you release Shift before WASD. If you keep pressing Shift after WASD the character starts moving to the mouse cursor. This is obviously unexpected behaviour because I want to play WASD instead of mouse movement.

Solution:
Add a checkbox to disable mouse movement OR add a “keyboard only” setup that has mouse movement disabled (but do NOT completely disable mouse so we can still select items with mouse and stuff like that).
