Commented Unassigned: Build fails with long filename error [862]

Hi,

NTVS Version: NTVS Dev 2014-03-12 VS 2013.msi
VS Version : Visual Studio 2013 Ultimate

I have a simple Express app that is using the "googleapis" package. On build, it tries to copy into the obj\Debug folder but errors with the following:

```
Error 1 Unable to copy file ".\node_modules\googleapis\node_modules\gapitoken\node_modules\jws\node_modules\tap\node_modules\runforcover\node_modules\bunker\node_modules\burrito\node_modules\uglify-js\test\unit\compress\expected\assignment.js" to "obj\Debug\.\node_modules\googleapis\node_modules\gapitoken\node_modules\jws\node_modules\tap\node_modules\runforcover\node_modules\bunker\node_modules\burrito\node_modules\uglify-js\test\unit\compress\expected\assignment.js". The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.

C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\Node.js Tools\Microsoft.NodejsTools.targets 74
```

Note sure how you guys will overcome this OS limitation :)
Comments: We're not sure either... :( We have some battles to fight with the MSBuild and/or Windows teams. For now, what we can do is issue clear warnings as early as possible, and ask people to store their code in a short folder path.
