[Suggestion] Save Control Option

I would like to suggest the option of saving and loading the keyboard control options and layouts. So like, when you go and change your control settings you could hit a 'save' button and name the preset for the controls, and be able to just hit the preset to load up the controls you are looking for, in the newer versions. 

For example, I have my sprint key changed from ctrl > Q, and my drop key changed from Q > Y, due to having carpal tunnel in my hands and reaching my fingers to the ctrl key some days is actually very painful. I typically switch back and forth between snapshots to the latest version, and occasionally older versions for some servers. When I move back and forth through the versions I have to relayout all my controls again.

I understand this is a very minor change (and that it wouldnt really be a priority) and for some users might not even change their experience playing the game, but I do believe it would be a convenient addition.
