Markdown support in map comments

You can now use Markdown in the review system’s comments. Play with it at 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.
