/**
* A script to embed vimeo videos via the site (so vimeo privacy restrictions by domain will work in the mobile app).
*
* The site is doing a double frame embedding:
* - First, the media player replaces the vimeo link with an iframe pointing to vimeo.
* - Second, the app replaces the previous iframe link with a link to this file that includes again the iframe to vimeo.
* Thanks to these changes, the video is embedded in a page in the site server so the privacy restrictions will work.
*
* Note 1: Vimeo privacy restrictions seems to be based on the Referer HTTP header.
* Note 2: This script works even if the plugin is disabled (some users could be using the vimeo embedding code).
