News and _includes tree structure

I separated the _includes into:
- atoms
- molecules
- organisms
- _database (for a fake working news page)

All files directly in /_includes are considered patterns
All files directly in / are considered pages
So we have our 5 levels.

So, previously /_includes/form.php is now /_includes/organisms/form.php.

Nt much .less for the moment.
Tell me what you think.

(disclaimer: I'm really not keen about the php + html mixup myself but feel inconfortable making everything static when you're supposed to deal with template and data -- what organisms, molecules and atoms are).
