* AreaFix updates:
- No longer accepts AreaFix requests to "SBBSecho", since we send mail from
  that name, accepting mail to the same name can create a bot-loop
- Each linked node has a configurable "name" now, where to send notifications
  (not always "sysop")
- AreaFix support for a node can be toggled without clearing their AreaMgr
  password
- Area listings now include the echo descriptions (when available)
- Fix: the badecho is not included in area lists returned via netmail
- Improved log output around AreaFix requests/operations
- %echostats [echo] command now supported to request most recents stats for
  an area
- Notifications can now be toggled by AreaFix sysops using %NOTIFY On/Off
- Notification mail to the local Area Manager (sysop) now have the correct date
  time/zone in the message header (not copied from the AreaFix request)

* Added support for auto-responding to PING NetMail requests
* When exporting EchoMail, if the date/time written or imported exceeds the
  configured maximum age for EchoMail, don't export it (rescan exempted)
* The -g (generate notification messages) works with a passed address now
* Better grunged packet detection (e.g. NULL-terminated header fields must be
  NULL-terminated)
* Avoid bot-loop by refusing to send netmail from "SBBSecho" to "SBBSecho"
  If you setup an echolist to forward areafix requests to your hub a loop could
  occur :-(
