Move atoms components into the atoms folder

When I got to a point where I wanted to modify the base content it took me a while to figure out where they were coming from and the best way to modify/overwrite the content. Do I fork the style-prototype repo and update the bower reference or is there an simpler way?

I ended up realising that I could just copy the folders over to the atoms directory, which is kind of obvious once you realise that's the magic, there's no reason to learn this if you use the sub-generator to create patterns.

It seems like an improvement for newbies and a good demonstration of functionality that is otherwise abstracted away.

What do you think?
