[firefox upgrade] Replace action chain with tinymce JS.

HOL-12 HOL-29 rss_proxy djangoapp

HOL-36 Allow for override of course listing in index.html

use native JS tinymce to set the content.

Indicator-container div apply to status

On the older firefox version (28), the offset approach fails. This
update is being made as part of an effort to upgrade to firefox 42
incrementally. So we are including logic for Firefox 28 vs 42 that
we can remove after the upgrade.

Ensure old audit certs don't get marked ineligible.

Changing a field name in the way that we did (updating the Python
variable name and switching it to point to the old DB column) confuses
Django's migration autodetector. No DB changes are actually necessary,
but it thinks that a field has been removed and a new one added. This
means that Django will ask users to generate the migration it thinks
is necessary, which ended up with us dropping data. The fix is to run
the same migration on Django's internal model of the DB state, but not
actually touch the DB.
