Nes: Option to detect and use Zapper/accessories automatically when loading rom.

Mesen does it, and it's very useful. You load a rom, and then, the zapper pointer is there.

This would need to be a GameDB change, most likely. Since not all games use the Zapper.

Now we need a special section in the config for people to disable things we're doing automatically for them which might sometimes not be what they want.

I don't like it when emulators do this.
