new NuGet ver 2.5 build process, add win azure

* Added new windows azure projects.  These have been tested in a real
application already.  But they were refactored to a new namespace as
part of this move.
* Updated .nuget folder to contain NuGet 2.5 which can now automatically
build packages with correct package references to project referenced
assemblies that have a nuspec file.  This is a new feature to NuGet 2.5
* removed all the old build process
* Now each package can version independently, instead of having a
solution version - one of the big advantages to this new build process.
