ETreeViewFrame embeds a GtkTreeView in a scrolled window and adds an inline-style toolbar beneath the scrolled window which can be hidden. The inline-style toolbar supports "add" and "remove" actions, as well as move actions if the tree view is reorderable and selection actions if the tree view supports multiple selections. The action set can be extended through e_tree_view_frame_insert_toolbar_action(). This also adds a small demo program: test-tree-view-frame
