Add node.js compatability to the QML runtime

I'd like to suggest adding to the QML runtime Javascript Engine Node.js emulation/compatibility. In other words, add the missing bits that would allow almost any Node.js module to run in the QML Javascript Engine with no modifications.

Adding this would make all of the modules in NPM immediately available for use in QML. That would be an amazing productivity boost to QML application development.

Including automatic support for specing, installing and packaging these modules along with a build would be icing on the cake.
