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. 
Okay, so implicit ordering was removed in 2.1.0 for reports, I can see this. We back-ported it to v3 also because without this our changes would have been difficult. So its was mildly cheeky, but easier this way if I recall the reasoning. We've done this already for a lot of endpoints this might be one of the last ones.

For 1.6.x, the implicit order still applies but for v3 only obviously.
