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.
Do we need a test for "doRDFa: false"?
