    sourceview: Fix GtkSourceView tab width property binding (bgo#738001)
    
    The tab-width and indent-width properties interact weirdly if they're
    different. This was a breakage in the GtkSourceView 3 migration, so
    just switch the binding back over here.
    
    This might cause some pain in the future if we want to support setting
    both for some reason, but I don't actually know why we'd want to do
    that.
