The Twitter module implements Twitter support for BarnOwl. It also
supports automatic mirroring of some subset of Zephyrs you send to
Twitter.

To configure it, first

* Add your twitter credentials to ~/.owl/twitter as a JSON hash, e.g.
{"user":"nelhage", "password":"sekrit" }
* Load the module (cp Twitter.par into ~/.owl/modules and :reload-module Twitter)
* Set the twitter:class, twitter:instance, and twitter:opcode
  variables to the destination you want messages to be mirrored
  from. By default, they are -c $YOUR_USERNAME -i status -O twitter
  Setting twitter:opcode to "" will cause "normal" (i.e. no opcode)
  messages to that class/instance to be mirrored. A value of '*'
  works as a "match-anything" wildcard for any of the fields.

Twitter.par will also receive twitters and inject them into barnowl as
messages of type 'twitter'. It polls for normal messages once a
minute, and direct messages every other minute. To disable polling,
you can unset the 'twitter:poll' variable in BarnOwl.
