All live preview logic has been moved to ve.ui.MWLiveExtensionInspector so
so this can be simplified down to just static configuration.
Depends on I708c4cb012be in VE-MW.

As we can't access the view node we have to use stagin transactions
to apply changes to the real document node.
In all cases we can now bypass the parent teardown method as the
model has already been updated.
Depends on If1250402f266 being pulled through to the VE extension.
