Modular sample app is out of date for styleguide recommendation

[AlexMcConnell]

The modular sample app is recommended for seeing the styles in the style guide in action, but it doesn't really seem to follow the current style guide very well. None of the services follow the .service.js naming convention, the core config file assigns itself to a variable which is reused in the file, the unit tests are in their own folder, etc.
