merged in code from em_folder_tree_model_drag_data_delete.

2004-02-09  Not Zed  <NotZed@Ximian.com>

        * em-folder-tree.c (tree_drag_data_delete): merged in code from
        em_folder_tree_model_drag_data_delete.
        (tree_drag_data_get): similar.
        (tree_drag_data_received): similar.
        (drag_text_uri_list): removed, use em_utils_selection_set_urilist
        in tree_drag_data_get instead.
        (em_folder_tree_enable_drag_and_drop): merged in
        em_folder_tree_model_set_drag_drop_types.
        (tree_drag_motion): merge in drop_possible, handle qualifiers, and
        return the right type.
        (em_folder_tree_model_row_drop_target): rename to
        emft_drop_target, and make private.  Beefed up substantially,
        handles illogical drops, dropping on to special folders and
        properly handling vfolder uri's (at least within the same tree
        instance).

        * em-folder-tree-model.c: Moved all of the DND stuff to
        em-folder-tree, where it belongs, made it all static.  Should
        allow for some sharing of code too.
