Edited Issue: Change "Global Modules" to simply "global" [859]

Hi,

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

The node web application templates now have a "Global Modules" folder under npm.

There are two problems with this.

* The pascal casing does not agree with the lower or camelcase of "npm".
* The term "Modules" in "Global Modules" is superfluous because developers expect to only find modules under the npm folder.

Consequently, I suggest changing "Global Modules" to simply "global"

In general when dealing with JavaScript it's best to go along with camelcase as that is standard.

Thanks.
