- Added a lot more detail for outbound echomail and netmail (msgs, packets,
  and bundles) to help identify the source of problems
- Removed a lot of unnecessary "status" type log output ("Scanning for ...")
  as it was back in 2005.
- Date format in log is more standard (year-month-day)
- Logs error level and import/export statistics when exiting
- Packs bundles *before* writing to FLO files (the only operational change).
- sbbsecho.log should actually be smaller (grow slower) though there is more
  helpful information than before.
- Incremented version to 2.31.
