Allow full screen on iOs (web app)

Add meta to index.html, to allow iOs to display webapp in full screen mode:

    <meta name="viewport" content="initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=no, width=device-width, minimal-ui">
    <meta name="apple-mobile-web-app-capable" content="yes">
