Added MKE words to dictionary.

* Added MKE transcript to archive + various emails to tlhingan-hol with
  other people's transcripts of MKE.

* Changed aircraft attitude words {HolQeD} 11:2 into stative ("to be")
  verbs. They were not very clearly defined there, and new usage of {ron}
  and {ronmoH} (as well the very few examples given in the {HolQeD}
  article) seem to indicate that these words function as stative verbs.

* Updated list of sources for the pocket dictionary to include TNK and MKE.

* Added transcript header to an old transcript (1998-05-28-email.txt) which
  was missing one.
