First cut at implementing support for:

* sending hipchat messages as HTML.
* setting background color of hipchat messages
* flagging hipchat messages to "notify"
* ability to change who the message shows as being "from"

These are done through using text fragments in the message being sent - for example if using this hipchat adaptor, you then do this:

mmbot echo ::format html ::background random This text will be <b>bold</b>

Then you will have echoed back an HTML foramtted message with a random background color (so <b>bold</b> will render as bold in the clients).

Still needs more work + need to implement support for one-one-messages (currently only works for group chat e.g. room messages).
