Add an option to restore PPSSPP's settings to default.

Can be handy on platforms which don't have access to the ini file(Android..) without being rooted or if it's in a place not normally accessible for some reason.

It does not overwrite the user's control mappings or bindings. It's tucked under Developer Tools and includes a prompt screen so the user doesn't do it by accident.

I know more options aren't always the best, but something like this sort of goes without saying, I think.
