Option to skip the alert on quit from games

[illando]

It could be useful to add an option in the settings to turn off the iOs alert that is present when you exit from a game that says "Are you sure you want to exit the game".
Now that the new Save/Load command can be activated from the MFI controller without removing hands from the controller, this is the only command that still need to use to touchscreen if you want to change game.

Thanks.
