Domain roles now stored in nohist_domainroles.db file in /home/httpd/lonUsers/$dom on library servers in domain.  To be switched to storage on a single "primary" library server.

lonnotify::print_display_option_form() uses contents of nohist_domainroles.db to present choice of Domain Coordinators when selecting options for display of sent mail.

lond routines added for storage of broadcase dcmail.

Future consolidation of put/dump lond routines for domain-level db files is desirable.
