CustomizableUI.createSpecialWidget creates and returns a document element. For the tpaint/ts_paint talos profile, there's a spring in the toolbar-menubar that needs to be created everytime.

I've been experimenting with making it so that after the first spring is created, we cache it, and do document.importNode on it instead of creating a new one.

Local testing is a little noisy, but it *might* gain us some time.

This is no longer necessary now that the spring has been removed from the talos localstore.rdf (bug 903044).
