* Added archive verification when loading package metadata for -u and -A

operations (now aborts on a corrupt archive)
* Fixed the pm_fprintf newline error that was plaguing us.  It seems a line
  resetting 'neednl' was removed a while back (by me).  This causes all the
  output errors we've been seeing
