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.
If you look at headers, doRDFa is defined to `true` if it's undefined. Otherwise, it is whatever value is provided. If it's anything other than false, this should evaluate true in typical usage:

    if (conf.doRDFa) { ... }

This will cause RDFa to be generated if they specify it as "1.1" (or "1.0", for that matter). If the set it to `false`, it will evaluate to false and not be generated.
