Update package.json

ENYO-2045: Went through https://npmjs.org/doc/json.html and updated it to include our dependencies and fix the repository link.  Will need to check to see how npm installs this, as I suspect that all the node modules will now be off the top-level, meaning tools scripts will need changes.
