Add assets folder for a cleanier app folder hiearchy

This make it easier to maintain than having all in the same app root folder.

Have always debated this one, think it depends on the size of the project - though we can assume for the most part it'd be cleaner to contain the folders in an assets folder. I'll merge this with the next update as well as the other kind pull requests - thank you for contributing!

I’ve been between the two schools for a long time. But for the last few projects I’ve been working on, I always find it easier to have only one kind of file/ressources in a folder. I find it easier to find what you’re looking for when there only templates on the root folder for example. We could also have move the favicon and the apple-touch-icon in the asset folder by referencing them, but I like when we didn’t had to declare them in the head of your page.

Yeah, agreed. On our AngularJS projects it's easier to have assets, views, templates folders then there's no confusion and cleaner to see. I thought about moving the icons across, but then that adds more markup for really no reason at all. Am set on that for now at least, H5BP is pushing that route too.
