GetFirstActivePadConfig returns a dummy config if nothing is connected, which
didn't have any of its arrays created. Fill in dummy arrays for enabledSensors,
etc. so refreshes don't throw exceptions if they're updated right when the
last controller disconnects. (This is a rare race condition and I've only
seen it while stepping in the debugger and disconnecting while stopped.)
If this is used to play GIF animations on the pad, being able to have
it launch on startup is useful.
This is disabled by default and there's no UI to enable it yet.
