Just like Moodle Docs appears in all footers on themes unless they ignore it or disable it , we should have a "Get Moodle on your Mobile" link appear and link to a landing page with the information related to getting it (not the common one, explain later). This will show no matter if the user is using a mobile device or not - so is very different to smart banners.

The URL that they link to can be overridden in the settings if they have their own mobile app - so this setting should be a URL.

Only show if mobile services are enabled and the URL is set.
