Updated Autofac registrations

I have updated the Autofac registrations to use the recommended lambda syntax and fixed the capitalization of the container name. When first compiling the fork I received some compiler errors, and upon first run also got a NullReference exception. It looks like another pull request already covers those fixes so I have left them out of this pull request.

This is a great testing tool, not just for the wider developer community, but for container developers too. Cheers!
