Feature: translate C-Buttons as Smash/Aerial Attacks

[the-outcaster]

Allows the player to set the C buttons to smash attacks, or aerial attacks if the player is in the air, as opposed to the default jump behavior. Makes it more akin to the later Smash games where the user can easily tilt the right stick to perform a smash attack.

A check is made to make sure this is only applied while the player is in the game; this ensures that the player can still adjust the character's color palette in the CSS with the C buttons without causing erratic behavior (i.e. the cursor snapping in a certain direction and hitting the A button at the same time).

If the user has tap jump disabled, this can be a problem though since they won't have any way to jump otherwise. As a compromise, I added a second toggle underneath that converts D-pad input to the C buttons. This way the player can map a button, such as X or Y on a Xbox-style gamepad, to any of the D-pad directions, and give them their jumping ability back.

Note there are some weird edge cases I've tested where, for example, the character will still jump as opposed to performing a smash attack, depending on how the stick was tilted, or the character will do a forward air attack when tilting down on the right stick immediately after jumping.

Also took the opportunity to re-organize the enhancement options in the menu a bit.
