C-stick nairs + remap strong in air controller option#843

having an option to do a nair/jab by hitting the diagonal on the c stick would be nice, similar to brawl and sm4sh. off by default, but given that air grab does a nair, i think its fair.

also i think similar being able to rebind grab and parry in the air to different functions, i think you should be able to do the same with the strong button.
