Add instructions to uninstall and revert to original joystick order

[kvnvallis]

I can uninstall the joystick-selection package from the RetroPie-Setup script menu, but after I uninstall and reboot, the last-used joystick order is still in place. What do I need to change in order to restore the default order? If you can point me toward which config files are modified by your joystick selection script, that would help me get started.

I found a solution. You can change the joystick order in the Configuration Editor.

EmulationStation > RetroPie > Configuration Editor > Configure basic libretro emulator options > * > Choose joypad order
