      The HipchatAgent sends messages to a Hipchat Room

      To authenticate you need to set the `auth_token`, you can get one at your Hipchat Group Admin page which you can find here:

      `https://`yoursubdomain`.hipchat.com/admin/api`

      Change the `room_name` to the name of the room you want to send notifications to.

      You can provide a `username` and a `message`. When sending a HTML formatted message change `format` to "html".
      If you want your message to notify the room members change `notify` to "true".
      Modify the background color of your message via the `color` attribute (one of "yellow", "red", "green", "purple", "gray", or "random")

      Have a look at the [Wiki](https://github.com/cantino/huginn/wiki/Formatting-Events-using-Liquid) to learn more about liquid templating.
