Add initial support for a Deployment custom post type

This post type will be used to track deploy hooks that are setup
with GitHub. In the future, we can hopefully use these to connect
to other VCS as well.
Redirect any template loading to our custom deployment handler
Register a post type for each deployment instance received
Kill the page load after the deployment instance has been captured
Capture and display deployment payload data.

I'm going to merge this early so that I can get the data that GitHub
sends in a deployment. This work is not done yet.
