* Ratelimit outgoing messages
 * Prettier config class, not just a Hash
 * .split on [:params][1] in scrape, to make it work with multiple uris on one line
   * somewhat done - prints title only for the first uri, to avoid flooding the channel
 * Per channel/network configuration
 * Multiple network support
 * content downloading in scrape in a separate thread to not make the whole client timeout on downloading a big/slow url
 * switch from open-uri and net/www to CURB (https://github.com/taf2/curb)
