Allow file extensions in MKTG_URL_LINK_MAP template keys
Set content type on requests for static templates based on the template key

Feature flagged. Puts a checkbox in the iframe. The iframe uses an organization_full_name parameter forwarded from Drupal by the courseware views and POSTs an email_opt_in parameter to the student views, preserving it on 403.

This way instead of having to explicitly add releases to the urls.py
file, we just add the relase to the static_templates/press_releases
directory and the right thing happens.

Getting rid of the current "feature" where /pressrelease redirects to
the current press release.  It was broken, looks like it's unused.

Limitation: release file name must match slug, but with underscores and
all lower case.

Why bother? I wanted to do something small to learn the edX toolchain.

Cleaned up the urls file a bit, to remove urls that don't work. Also removed some unused stuff from static_template_views.

Moved static template views to one folder. Removed the stub view functions from student and used static_template_views instead.

cleans up home page header design, adds social sharing to header, adds tos, privacy policy, honor code, help and copyright pages, add liks to those pages in footer, finished contact page

adds pressrelease page, breaks about content into seperate pages, imporvoves some visual elements of about and jobs pages
