Jul 2014 docs adjustments

Lots of fun stuff! This probably needs review before merging, to make sure I didn't slip up somewhere. 

We should also discuss where to merge it. Once we know whether the changes are good, let me know whether I should rebase onto stable or something. Ideally, I'd like to get these into 2.0, 2.1, and next. 
Yeah, you're right. I was reaching a bit, to try and shrink the less relevant part. I'll see if I can re-jig this.
