Original issue's description:
> Password bubble: ManagePasswordsIconView is now a BubbleIconView.
> 
> This CL introduces a new browser command to open the Manage Passwords bubble,
> and converts the ManagePasswordsIconView class into a subclass of
> BubbleIconView, which uses the new command to control the bubble's state.
> This allows us to more easily test the view and the UI controller, as each
> object's job is now more clearly defined (and the view is now doing a good
> deal less work), and to independently verify that the command is doing the
> right thing.
> 
> After this CL, we'll (finally!) have something approaching reasonable test
> coverage for the core of the views code.
