Ultra mega hacked in, by saving all "discarded" joysticks to an array so they don't get totally closed & we can still poll them. Events now properly send the device number instead of the player number, which means we can store all controllers pressing buttons, and thus, can detect when ANY controller is pressing anything, and THUS we can make the character select work like we wanted to :V
Did not bother fixing any of the bugs, however. First of all, the opening menus do not properly fallback to default controls. Yet again, we may need a more robust system -- storing all keys from gamekeydown separately? Additionally it seems like when I input gamepad it makes me use keyboard anyway, so I think something fishy is up.

This is NOT just a normal merge commit. I have adjusted the hotplugging code from stableid to account for the last two players, and also removed new 2.1 additions that were deemed irrelevant to Kart.
* Don't save cv_usejoystick/2 because hotplugging changes can be made invalid by next run
* Properly set cv_usejoystick/2 for menu toggling
* Force-disable a player's joystick if setting another player's joystick to the same device
* Properly set cv_usejoystick/2 value of BOTH target player AND other players when hotplugging and unplugging
