BIND export, unwinding dev saves, home stretch

  • Untwist pattern/standard for sub names to better align with tinydns export
  • File off a couple more places missing a FQDN terminating dot
  • Correctly set the "hostname" for NS records in a reverse zone
  • Refine looping over views on generation of BIND config fragment
  • Move generation and substitution of reverse zone name into zone file path down a ways for better error-catching possibility
