Phonecat tutorial does not follow style guide

[teropa]

The Phonecat tutorial does not really follow the conventions laid out by the Angular Styleguide.

In particular, I think the following rules should be applied:

• Rule of 1
• Folders-by-feature structure
• controllerAs View Syntax

It also might not hurt to explicitly refer to the style guide in the tutorial.

I'm working on the Angular 2 upgrade guide, and thinking of using Phonecat as the example app to upgrade. It would be less awkward if this issue was resolved.

I'm happy to work on this, but would first like to know whether you'd accept such changes.

I agree. PRs are welcome - but phonecat is a right pain to refactor due to the nature of it using commits as the tutorial steps

@petebacondarwin Thanks! I'll dig into it.

@petebacondarwin Looks like I'll need to make changes to some of the diagram images in the tutorial. Do you know where I might find the sources for them?

[petebacondarwin]

Hmm. Not sure. I'll see if I can find out
