        Patch from William Jon McCann <mccann@jhu.edu> in bug #105639.

        * panel-recent.c (clear_dialog_response):
        (clear_dialog_destroy):
        (recent_documents_clear_cb):
        (panel_recent_append_documents_menu):
        Add item to Recent Documents menu to clear the history.
        (panel_recent_model_changed_cb): Make the menu insensitive
        if no recent items are available.

        * panel-stock-icons.[ch]: add a new "clear" stock icon just so
        we can have a different mnemonic from GTK_STOCK_CLEAR. Suck.
