    symbol-tree: always expand the tree
    
    By default, the tree nodes are builded lazyly and async using
    a signal dispatched by the main loop, this make it hard
    to use gtk_tree_view_expand_all.
    
    We use the new construct-time "always-expand" DzlTree property
    to provide easily the same effet as we always want the symbol tree
    to be expanded.
