Updating to work with ASP.NET 4.5

Hi,

I'm preparing content for the Global Windows Azure Bootcamp next weekend and one of the things I wanted to show attendees was the AllInOne sample. The problem is it's actually broken at the moment because the dlls that were packaged with it didn't work on an ASP.NET 4.5 site.

I've taken the liberty of creating a fork that fixes this and also makes it easier to upgrade the files in the future by including a separate src folder with a Visual Studio solution and a generate.bat file that updates the deploy folder (I renamed the existing Source folder to deploy).

I upgraded to the latest MVC5 etc. bits at the same time and used the default Bootstrap layout for the index page.

The only thing I haven't done is update the documentation because unfortunately I don't have time with all the other prep I have to do for next weekend.

Feel free to pull this in or ignore if you don't like the approach I've taken - just thought I'd send through a PR in case you find it useful.
