[Xfce-i18n] Suggest changing "http://cdn.xfce.org" to "//cdn.xfce.org" in index.php

[scootergrisen]

In index.php i suggest changing:
$static_media = "http://cdn.xfce.org";

To:
$static_media = "//cdn.xfce.org";

That way if you test the website on https the media will also be 
transferred with https.
