Title: Added support for link_names in message formatting.

By default, when Slack receives a message returned by Hubot, it will not linkify channel names (starting with a '#') and usernames (starting with an '@'). This adds an environment variable that allows you to turn this formatting on (by setting HUBOT_SLACK_LINK_NAMES to 1).
