	** Fix for bug #318003

	* gui/memos-component.c: (selector_tree_data_dropped):
	* gui/tasks-component.c: (selector_tree_data_dropped):
	* gui/calendar-component.c: (selector_tree_data_dropped),
	(create_component_view):
	* gui/comp-util.h: (cal_comp_process_source_list_drop):
	* gui/comp-util.c: (update_single_object), (update_objects),
	(cal_comp_process_source_list_drop):
	Support move of the event in day view when dropped over the source
	list. Use the same function for events/tasks/memos.

	* gui/e-day-view.c: (e_day_view_on_drag_data_get):
	Encode string data same as memos and tasks do, with a source UID.

	* gui/e-calendar-table.c: (e_calendar_table_copy_clipboard):
	* gui/e-memo-table.c: (e_memo_table_copy_clipboard):
	Removed inappropriate comments.
