2001-05-21  Federico Mena Quintero  <federico@ximian.com>

	Fix bug #2831; the tasks toolbar and menu now have a button to
	delete the selected tasks.

	* gui/e-calendar-table.c (e_calendar_table_delete_selected): New
	function.
	(delete_cb): Use e_calendar_table_delete_selected().
	(e_calendar_table_get_table): New function.

	* gui/tasks-control.c (tasks_control_new_task_cmd): Handle the
	delete command.
	(selection_changed_cb): Change the sensitivity of the TasksDelete
	command when the selection in the table changes.

	* gui/e-tasks.c (table_selection_change_cb): Notify upstream when
	the ETable selection changes.
