Display output URLs as hyperlinks in Hipchat

By default the output URLs are displayed in Hipchat as plain text and must be
copy pasted into a browser. This change allows Hipchat to transform them into
clickable hyperlinks (by default, you can turn it off).

*Tech Notes*
Hipchat now allows API messages to be processed similar to user messages by
passing `message_format: text" in the API call.
