Featured events

[mattwynne]

The /events page is just a flat list, with no way for us to pull out events that we particularly want to promote. We need a way to curate a subset of those events that we want to promote in various places - sidebars on the blog, on the homepage, and either at the top of the events page or by highlighting them within the list.

TODO:

• Move events to our caching machenism
