Subject: [PATCH] CRM-21179 - visual-bundle.js - Generate custom build of dc.js

This defines an asset named `visual-bundle.js`.  It creates a custom build
of `dc.js` + `crossfilter.js` + `d3.js` which loads all the services into
the namespace `CRM.visual.{foo}`, which allows it to coexist with other
copies of the library.
