Allow installing apps via the AppBannerInfoBar
* 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.
