Enhancement request 3339. Added ability to store e-mail broadcast to users, and to retrieve e-mail, flitered by time window and/or senders. Expanded use of breadcrumbs. Improvements in display of e-mail receipt. Some work still required: add domain_roles_get() to lonnet; complete localization, complete work on breadcrumbs.
