This commit adds in course messaging for three use cases. First,
when the user is not signed in, the user is shown a message that
provides a link to sign in or register. If the user is signed in
but not enrolled, they are given a link to do so. If the user is
enrolled but the course has not yet started, they are shown a
message explaining when the course starts and shown a link (not
yet enabled) to add a reminder to their calendar.

The implementation defines a base message class and extends it
for the course home messages as well as the previously implemented
page level messages.

This story was to update the existing custom themes to work with the flexible bootstrap design. It also updates the red theme to more closely resemble the real implementation on openedx.

Footer HTML requested from the branding API was including two CSS files, lms-footer.css and lms-footer-edx.css. edx.org pages only require lms-footer-edx.css to render the footer. The template code being removed here appears to have been accidentally left in place during a theming change: https://github.com/edx/edx-platform/commit/c0648ab1642dfaece6f42fba9ce129e695b67b8c\#diff-439477a9ba29f7c208e25b0a535cdabeR80.

We have standardized the activation email in the base activation email body template, so we do not need this override any longer.

Datetime is used to make sure we never need to make a change like this again.
