This change adds a new "Related Courseware" section in the side
container; this section lists links to courses and talks that are
relevant to the current project page.
Relevant content is fetched by the browser, with an AJAX request sent to
the Pivotal Education LMS API. This API uses the Referrer HTTP header as
input parameter to its content selection algorithm.
Note that CORS HTTP headers are also used to allow/disallow AJAX cross
domain requests.
Flash support for ZeroClipboard is not working in project pages since
the SWF file is missing. There was a typo in the .gitignore file that
ignored "*.sw?" files.
