Added a server router and a simple test.

[tmeasday]

Some notes:

1. Had to mess with things a bit to get any tests running. I assume you will fix this somehow, let me know if there's something I need to change.
2. I understand the dispatch path better, and I have some general notes that I'll add to the hackpad.
3. In this instance the simple_route_dispatcher doesn't work server side as it does some client side stuff (rendering, waiting). Probably we need to do somethings in general though (filtering).
