C-Stick support on New 2DSXL

[papin97]

Hello. I tried the port and it looks very good (runs quite well), except I can't use C-Stick. Is this feature removed at some point? Also please add A button as enter button (to supplement D-pad as arrow keys) I use 3.0p2

I think I just forgot to add it into the rewrite, I will add it back in for the next update. Also I had an idea for the buttons that should satisfy everyone :)
