Implement upgrade notifications.

When we detect that the installed version is newer than the version you are
running we show a little throbbing orange dot over the wrench menu.

If you open the wrench menu and close it again, the throbbing will stop.

However, if you look at the contents of the wrench menu you'll notice that
the About box menu item has been removed and in its place is a menu item
"Update Chrome Now" with a bright orange icon to draw your attention to it.

Clicking on the icon shows a dialog box asking whether you want to restart
Chrome. If you do, the browser restarts with your session restored 
(even if you have Session Restore turned off).

Known issues:

- Currently this is Windows only. We'll have to port this to Linux and do
something differnet for Mac (which doesn't have the wrench menu).

- Showing an icon in front of Update Chrome causes the checkbox for the
bookmark bar menu to go away. Given that we will soon redesign the menus I'm
not going to spend much time trying to fix it.

BUG=27941
TEST=Wait for Chrome to be upgraded in the background, an orange dot should
appear over the wrench menu and if you select Update Chrome your session should
be retained.
