Cesium does not build with npm 1.3.10

[gberaudo]

There is no compilation error, but the build only takes half a minute and Cesium.js is missing from Build/Cesium. The build guide does not mention a minimal version of npm.

With npm 1.3.10

$ npm run minifyRelease

Thanks @gberaudo! We all use node version 4.2.2

@mramato is this a bug or do we need to specify a version of Node in the build guide?

[mramato]

We should specify Node 4.x or newer in the build guide. All earlier versions are soon to be end-of-life.
