Feature/rdfa lite

Update RDFa to use RDFa Lite only, unless doRDFa is explicitly set to 1.1, in which it also outputs `@inlist` on editors and authors. Removes RDFa 1.0 support, adds specs and fixes bugs.

This should make the default doRDFa="lite" to generate HTML which will validate without warnings.
No, that's all been removed. The fact is, except for editors being in a list, there's really not a reason to do the RDFa any other way. Markup is pretty much the same. In references, we did have some reduced markup because of @rel chaining, but it's hard to say that it's any better than the Lite version.

Certainly, if there's some reason to support 1.1 features, we can always go back, and of course, any editor can put their own RDFa in their specs. The strong sense I got from the conversation was Lite only within respec itself, and I think it worked out pretty well.
