N3/Turtle parser should recognize rdf:first rdf:rest pairs as lists

[timbl]

The turtle parser currently will accept the turtle list notation with parentheses, but will not accept lists in their reified from expressed as a set of lisp-like pairs off rdf:first and rdf:rest pairs ending with rdf:nil. It should convert them into lists as though they had been in the () syntax, and should remove then rdf:first and rdf:rest triples from the graph.

Probably good to make this an option, which happens by default.
