* Button cycles between "Install", "Installing", and "Open",
  depending on the installation status of the app being promoted.

* Clicking on the icon or the title of the AppBannerInfoBar should
  send the user to see details about the app that is being promoted.

* Open up access to LinkClicked() from ConfirmInfoBar.
  Piggyback on LinkClicked() to determine that the user wants to
  see the link related to the app.

* Add an ID to the icon of the infobar so it can be retrieved and
  have an OnClickListener attached to it.

* Update the status of the button when the user hops in and out
  of the Chrome application.
