* Descending required build tools chain v142 -> v100. Actually, require Visual Studio version < Visual Studio 15(I use Visual Studio 2010).
* Add more macro for Virtools.props
* Solve build error for standalone version of Virtools 5
* Finish mk_materializer_cfg.py with all possible options
* SuperScriptMaterializer now load Virtools.props to define how the entire project should be compiled
* Move includeing path, lib path and etc to a specific file Virtools.props
* Add mk_materializer_cfg.py to change Virtools.props for more build configuration
* Ready for multi-virtools-version development
