Title: First step source source file mapping

This commit is the first step towards source file mapping. I'm offering it up now in case you want to get it merged in while I figure out the least disruptive way to track the JavaScript source code generation side of things. Also if you'd like it coded a different way now would be a perfect time to find out. :)
