Add all dependencies to package.json

[piranna]

Template dependencies are in separated files, so greenkeeper can't control them. I propose to add them as dependencies or devDependencies so they can be check and updated automatically, and later select the ones that need to be installed on the project instance from some lists, similar to what I'm doing with user dependencies on NodeOS.

Thats a really good idea. I'll try to do something like this.

If you need some help, my buildDependencies module can be useful, or at least being used for inspiration.
