Key events hack

This is a one day hack to experiment with a key events panel in live blogs. The hack uses the layoutHints -sp- url slug hack to direct all traffic to the blog of that piece of content.

If successful (i.e. people use the component) we will consider building it for real in the up coming live blog redesign.
