Title: Bower: fetch transitive dependencies v.2.0

@gaurave, @devoncarew

Download transitive Bower dependencies in 2 stages:
1) Using XHR, recursively read hyperlinked bower.json's starting with the project's top bower.json. Accumulate uniquified global dependencies of the project.
2) Downloads the resulting set of dependencies in parallel.

I'm going to add code comments tomorrow.
