mod_account_activity: Record an account's last activity timestamp This is similar to mod_lastlog/mod_lastlog2. Some functionality was dropped, compared to mod_lastlog2. These features (recording the IP address, or tracking the timestamp of multiple events) are handled better by the mod_audit family of modules. For example, those correctly handle multiple logins, IP address truncation, and data retention policies. The "registered" timestamp from mod_lastlog2 was also dropped, as this has been stored in account_details by Prosody itself since at least 0.12 already.
