Very crude dispatch cycle is working now.

The code is pretty simple right now as it doesn't attempt any fancy
footwork around mocks or giving you ways to only get the just the view
without the layout. It is also not possible to get the view variables
just yet.

I've also added a stub response to smooth over any issues where someone
might try and send a response by accident or on purpose :)
