Set a pref so we only do this once. @fbennett - have a look, I think this was really the last step we needed to make this foolproof, so I'm excited to have it running, but I'm very inexperienced with this - first time I'm touching an add-on - so it'd be nice if you could make sure that I'm not doing anything foolish. I'm not attached to any of the labels, so if anything bothers you, just fix it.
