Don't delete controls #121

Is your feature request related to a problem? Please describe.
in the options screen, pressing "configure" deletes the player's existing control scheme before a player sets them. if a player presses configure and then back to the previous screen then all controls are blank. the same thing happens when pressing "reset" and then "confirm?".
for me this is un-intuitive behavior.

Describe the solution you'd like
when pressing "configure" i don't want the controls to be deleted before a player sets them.
when pressing reset and then confirm i want the control scheme to be reset to the default.

Describe alternatives you've considered
