Improve, broaden, and update support for XEP-0136 and XEP-0313
Description
Openfire has (rare!) support for XEP-0136, and a powerful monitoring plugin that provides utility above and beyond simple message archiving. Some support for XEP-0313 has been added, but this needs updating. In principle, the baseline support for archiving already in the product should provide us with the foundation for an excellent archiving solution covering full modern support for archives in chatrooms, pubsub nodes, etc.
