Nuget Packages Updated

I updated my nuget packages to support Visual Studio 2017 (v141):

• GLFW – https://www.nuget.org/packages/glfw/3.2.1-v141to2015
• Lua – https://www.nuget.org/packages/lua/
• voro++ – https://www.nuget.org/packages/voroplusplus/

Using this opportunity, I dropped support for Visual Studio 2010.
