Provide option to add authentication while creating project

[Im-PJ]

It would be very nice if there is an option of adding authentication code like when creating default MVC project. adding asp.net identity authentication later on is pretty cumbersome and defeats the purpose of using template to get started easily.

For my personal use case I didn't need that functionality as I already had another auth setup, but that would be a nice addition. I wouldn't want that to be something that's forced on the user, though. It would have to be an option like the default web project dialog in VS.

That said, I don't really have much time to commit to looking into how to accomplish that but pull requests will be considered.
