** Fixes bug #542587

2008-07-20  Matthew Barnes  <mbarnes@redhat.com>

	** Fixes bug #542587

	* shell/e-shell-window.c: Use new EOnlineButton widget.

	* widgets/misc/e-online-button.c:
	* widgets/misc/e-online-button.h:
	New widget implements the online/offline button used in the main
	window.  The button just maintains an "online" flag and displays
	the appropriate button image for the flag.
