Make the "Select" button bindable#1775

It’s a whole other button on the controller which does nothing in-game except for turning on hitbox display in replays (which the binding wouldn’t interfere with) or training mode (where it can also be turned on through the menu). When there are so many good button macros available (strong, short-hop, walkmod, parry, all-taunt) and only so many buttons on the actual controller, being able to use this button for something in-game would be a godsend.
