A portable way to populate THANKS.

In particular:
 - BSD sed and GNU sed dosagree on commandline options.
 - echo "\n" >> FILE or "\r\n" for that matter, does not create a
   newline in FILE on Windows.

Original patch by Christopher Bonhage, applied with slight modification.

Closes COUCHDB-1628.
