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.
They are the same, and at this point, I believe, "dc" is in wider use, it also makes it shorter. "dcterms" was used as a more provisional prefix when we were transitioning from the use of DC Elements to DC Terms. Now that the transition has happened, the "dc" prefix is more commonly used. Of course, the resulting RDF remains unchanged.
