[TF-ENT] Updates to RIF Entailment section

From: Chimezie Ogbuji <ogbujic@ccf.org>

Birte, all.

I made changes to the RIF entailment regime (in the SPARQL 1.1 entailment
editor's draft document) mostly in response to Jos's comments [1].
Primarily, the semantics of answers are now with respect to the merge of the
scoping graph *and* any graphs imported (with the Simple profile) into the
referenced, safe RIF document.  Also, the rif:imports statement is not
included.  The language regarding common RIF-RDF interpretations,
satisfaction, etc. has been clarified.  The editorial note regarding safety
and its relationship to Condition 4 has been removed since it appears
(through various comments, etc.) that uniqueness and the exclusion of
(trivial) infiniteness can be guaranteed with certain safety criteria (at
the expense of expressiveness of the language).

The paragraph describing stratification methods for ensuring finite answers
in the face of cyclic dependencies in builtins has been removed and that
paragraph has been shortened.

I'm still not satisfied with the text regarding summarizing the balance
between sacrificing interoperation and query safety for a more expressive
power.  Hopefully, I'll have a brief paragraph to add to the informative
section later this week.
