Markdown support in map comments

You can now use Markdown in the review system’s comments. Play with it at http://daringfireball.net/projects/markdown/dingus. Added it so links are linked. That does not happen automatically, you have to add <> around them or use the ]() syntax.

Only comments posted after right now are parsed for markdown. Older comments would break.

It should be secure, I am filtering things. Please don’t waste my time trying to exploit it.

We’ll see how it works out.

Looks useful. Do images work?

Yes but only because I have not disabled them yet. I might leave them enabled but if people start using them for unrelated clutter or huge files they will not survive for long.
