Added support for VS package references for nuget
Microsoft added the possibility to declare nuget package references directly within project files : https://docs.microsoft.com/en-us/nuget/consume-packages/package-references-in-project-files
I made a minimalistic implementation with which you can use
set_property(TARGET ${TARGET_NAME} PROPERTY VS_PACKAGE_REFERENCES "boost_1.7.0")
to be able to define such packages.
You can either restore the packages via command line or right click on a an openend Visual Studio Solution and use "Restore NuGet Packages". No need to point to the specific dll's - that's taken care by MSBuild.
