Add TweetUrl plugin

This plugin matches for messages of the form

  <url> # <comment>

eg:

  http://www.kittenwar.com/ # kittens!

and posts them to the configured Twitter account along with
the author’s nick.

This allows Funkbot to use Twitter as an archive for interesting URLs.

The required Twitter API keys can be generated for an account at
https://apps.twitter.com/ by creating a dedicated app for the bot to
use.
