added little buttons which are shown when there are more events than will

	* gui/e-week-view.c: added little buttons which are shown when there
	are more events than will fit in a day. Clicking on the button takes
	the user to the 1-Day view and shows the full day.

	* gui/e-day-view.c:
	* gui/e-week-view.c: set the "use_ellipsis" arg to TRUE for the EText
	items so we get tooltips automatically. Though we may want to use our
	own code to show tooltips so we can show the tips when the mouse is
	around the edges of the event box, and we may want to show the start
	and end times of the event in full.

	* gui/calendar-commands.c (calendar_control_activate):
	* gui/gnome-cal.h: added view_toolbar_buttons[] so we can access the
	radio buttons in the code easily. We need this if we want to jump to
	another view programmatically.
