Files in /node_modules should be be included in the warnings/errors

[belav]

I have an mvc5 project that has the following files that are being reported as "Project is not referencing them" node_modules\node-gyp\lib\Find-VisualStudio.cs node_modules\node-sass\src\libsass\win\libsass.sln

I believe that everything within a node_modules folder should be ignored by this plugin.
