simple markdown support for chat

[drivver44]

it would be useful for mentors to have markdown formating when it comes to messages often things like how to rename room follows

• you need to !boss yourself first
• then do $rename namehere

would be better to look as

• you need to !boss yourself
• then do $rename

If we implement this: we should avoid rendering the headers [#]. The larger text could be abused / obnoxious in chat.
