In case someone wants to be very careful with how much bandwidth
they use or with what data GameTDB.com collects on you.
This is already an option in DolphinQt (though in DolphinQt it
will switch entirely from using covers to banners when turned off).
Other than the controller settings and JIT debug settings,
these are the only settings which were defined in Java code
but not defined in the new config system in C++. (There are
still a lot of settings that are defined in the new config
system but not yet saveable in the new config system, though.)
