Features

• Waitress now has a main and thus may be called with python -mwaitress

Bugfixes

• Waitress no longer allows lowercase HTTP verbs. This change was made to fall
  in line with most HTTP servers. See No longer allow lowercase HTTP methods Pylons/waitress#170

• When receiving non-ascii bytes in the request URL, waitress will no longer
  abruptly close the connection, instead returning a 400 Bad Request. See
  Fix issue #64 Uncaptured exception instead of 400 when receiving non-ascii bytes in request url Pylons/waitress#162 and
  Uncaptured exception instead of 400 when receiving non-ascii bytes in request url Pylons/waitress#64
