        Fixed bug 51917, add atk support for ClickToAdd

        * gal/a11y/e-table/Makefile.am: add files.
        * gal/a11y/e-table/gal-a11y-e-table-click-to-add-factory.c:
        (gal_a11y_e_table_click_to_add_factory_get_accessible_type),
        (gal_a11y_e_table_click_to_add_factory_create_accessible),
        (gal_a11y_e_table_click_to_add_factory_class_init),
        (gal_a11y_e_table_click_to_add_factory_init),
        (gal_a11y_e_table_click_to_add_factory_get_type): factory
        for ClickToAdd
        * gal/a11y/e-table/gal-a11y-e-table-click-to-add-factory.h:
        ditto
        * gal/a11y/e-table/gal-a11y-e-table-click-to-add.c:
        (etcta_get_n_actions), (etcta_get_description),
        (etcta_action_get_name), (idle_do_action), (etcta_do_action),
        (atk_action_interface_init): a "click" action interface.
        (etcta_get_name),
        (etcta_get_n_children), (etcta_ref_child): create accessible
        according to which child is available. Either rect or row.
        (etcta_class_init),
        (etcta_init), (gal_a11y_e_table_click_to_add_get_type),
        (etcta_event): listen to canvas event, emit children-changed signal
        when it found rect/row was changed.
        (gal_a11y_e_table_click_to_add_new):
        * gal/a11y/e-table/gal-a11y-e-table-click-to-add.h:
        * gal/a11y/e-table/gal-a11y-e-table-item-factory.c:
        (gal_a11y_e_table_item_factory_create_accessible):
        * gal/a11y/e-table/gal-a11y-e-table.c: (init_child_item),
        (et_get_n_children), (et_ref_child): change the trick way to
        create a11y object for a table item. Because ClickToAdd is also
        a table item, previous way do not work for clicktoadd.
        * gal/e-table/e-table-click-to-add.c: (etcta_class_init):
        atk_register the new a11y factory.
