This only covers constant rate rate adjust mods. Mods like wind up/wind
down will need a more complex implementation which we haven't really
planned yet.
Turns out the only check required to get into this screen was that the
API was online, which it always is even if the multiplayer component
isn't.
This provides a better end-user experience.
Until now the disable setting would only apply to left/right buttons,
and only in gameplay. This change will cause any global actions bound to
mouse buttons to also not work during gameplay.
