Community_News/.make_email.cfg: Removal of the SQLite database
reference. No longer needed.
Community_News/make_email: A lot of updates relating to confusing
variable names. Rationalising the three code paths to compute the
recording date (-date=DATE), the review month (-month=DATE), and
the default using today's date to determine needed date
information. Removed all references to the database because we
don't need it any more. New date computation functions. A lot of
POD updates, including an EXAMPLES section.
