Fixed solution and project files so the build will work with .NET 3.5.
Migrated to automatic package restore as per: http://docs.nuget.org/docs/workflows/migrating-to-automatic-package-restore
Added unit tests to the build script so the build will fail if any unit tests fail.
Updated README.md to include building instructions.
