* Fully reimplement the MenuColor system from 2.2's codebase, so super and emerald colours are now inaccessible again.
* Add FOLLOWERCOLOR_ constants and internal loop support to M_GetColorBefore and M_GetColorAfter.
* Fix improper initialisation of certain menu colour data.
* Repair previously created (or manually-edited) profiles with invalid colours.
* Add an actual function to turn followercolor constants to effective values.
* Previous control checking flow:
* Current controller/keyboard (userbound controls).
* If on a menu:
* Current controller/keyboard (default controls).
* All controllers not in use by a player (default controls).
* New control checking flow:
* Current controller/keyboard (userbound controls).
* If player 0 and just checked a controller, check keyboard (userbound controls).
* If on a menu:
* Check all controllers not in use by a player (userbound controls).
* If keys are inaccessible/unbound and keybind is necessary to navigate menus, repeat eveyrhting with default controls.
* Instead of duplicated code, control the flow in a finer fashion.
* Now able to detect if gamepad inputs are possible to recieve (via checking deviceID), instead of assuming they are.
* If a keybind is set but inaccessible by the above metric, make it flash on the Profile Controls screen.
* Fix out-of-order key mappings for a given bind being invisible on the Profile Controls menu.
* Replace the shitty vidwait option with Sal's shiny new fpscap option.
* Update the item toggles menu for all the new items (and re-enable shitsfree for the new empty spots).
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.
