Community_News/reserve_cnews: brought this script out of the archive
where it had been placed in the expectation that Community News
slots would be reserved algorithmically on the hub. This script uses
the older strategy of placing dummy shows in the slots for the first
Monday of each month. The script has been updated and its internal
documentation improved. This version can find the next free
Community News slot and then create the requested number of
reservations thereafter.
