Fixed potential injection by switching map container to PHP

Browse source 
Some HTML files were importing iframe_api.js automatically by detecting the referrer document.

While this was done in a safe way (the map container does not use cookies), it is not
a best practice to load a script originating from document.referrer.

This PR solves the issue by using PHP to inject the correct domain name in the HTML files.
