Clarify config.js vs .jspm/config

[tauren]

The source file jspm-cli/lib/config.js appears to relate to two separate concerns. It deals with setting values into the global config file ~/.jspm/config and well as working with a project's config.js file. Unless these two concerns are intertwined, it might be better to break the file into two. This would help new developers to the project to better understand what each file is doing.

Definitely agreed that this file needs to be better structured (perhaps into lib/project.js for the package.json and lib/config.js for the global config and config helpers). The code also needs to be cleaned up as well.

Thanks - finally got around to this configuration refactoring.
