Added new sample projects and fixed Nancy

I had to fix the ctor in the AuthenticationService for Nancy, it's a hack job at the moment because it looks like Nancy's Tiny IoC is picking a greedy constructor based on a resent change. 

I'll refactor all this when I get to the appSettings configuration stuff. 

Removed the old Nancy projects, Added a new one. Added the new projects for MVC as empty. Will be migrating everything soon.
