Unsolved Markdown title support?

[unbug]

I actually like to write a external link in topic's title, so I think its might be good if we support markdown in the title. Do I need to write a plugin or there is a better way to do this?

In some places in NodeBB we might escape the title, which may make the raw title a little odd

It's definitely not a common use case that's for sure...
