Editorial changes

Another ton of editorial changes. This concludes moving the content for `noLegacyStyle` reshuffle. 

So - some good news: the spec is now 10 (yes! *t* *e* *n*) pages lighter ... at least in FireFox's print preview. 

Some bad new: there are a few things that I still haven't managed to fix... like the TCallControl is still around in a few places.  

Anyway, can fix those things over the next week. Would like to revert back to the main branch and push the changes the the Ed, if everyone agrees.
