Block for Table of Contents

Could be kinda cool to support automatically adding a linkable menu for all the sections at the top.
(You don't already support this right?)

Projectz doesn't currently support it. It is probably not one thing we need, but I can see for others it could be nice - so would make for a good use case and target for the plugin system.

How could it work? Perhaps rendering the markdown and looking for all <hX> tags? Rendering is needed as headers in code blocks would get filtered out into their htm entity codes. So read, write, render, read, write.
