added "get_selected_events", and "update_query" virtual methods.

2003-07-22  Rodrigo Moya <rodrigo@ximian.com>

	* gui/e-cal-view.[ch]: added "get_selected_events",
	and "update_query" virtual methods.
	(e_cal_view_class_init): initialize new virtual methods.
	(e_cal_view_destroy): destroy new private members.
	(e_cal_view_get_selected_events, e_cal_view_set_cal_client,
	 e_cal_view_get_cal_client): new functions.
	(e_cal_view_cut_clipboard, e_cal_view_copy_clipboard,
	 e_cal_view_paste_clipboard): merged clipboard stuff.

	* gui/e-day-view.c (e_day_view_cut_clipboard,
	  e_day_view_copy_clipboard, e_day_view_paste_clipboard): removed.
	(e_day_view_get_selected_events): made these private as the
	implementation of the 'get_selected_events' base class virtual method.

	* gui/e-week-view.c (e_week_view_get_selected_events): ditto.
	(e_week_view_cut_clipboard, e_week_view_copy_clipboard,
	 e_week_view_paste_clipboard): removed.

	* gui/calendar-commands.c (sensitize_calendar_commands): call
	e_cal_view_get_selected_events.

	* gui/gnome-cal.c: removed a lot of redundant code thanks to the
	above changes.
