Community_News/make_email: Many bugs relating to the review month versus
the recording date. Some of these must have been there for 12 years!
Rerwrote several parts and added a function for converting Perl date
formats. Added '-force' option to turn off checks when the script is
run in the month after a review month (not uncommon, but fairly
infrequent). Fix for writing bad records to the date cache file.
Updates to POD documentation.
Community_News/make_email_template.tpl: Added new shared variables for
the review year and month as opposed to the recording year and
month. Improved the text explaining the "handouts" versus the final
show notes. Removed the reference to the target show itself. This
used to be where the "handout" notes were written, then they were
replaced before show release. This isn't being done any more.
Community_News/recording_dates.dat: Updated with the correct recording
date (and time) for the review of shows in March 2025.
