[BLD] Shortcuts: Refined presentation syntax proposal for Const

As the pres-syntax showed up again a few times this morning and as we 
discuss it again tomorrow morning, I try to summarize:

We agreed in the May 13 teleconf [1] to some shortcuts, i.e.
the option 1a in 
Still, this needs some more clarification and fine-tuning, and also the 
rif:text issue doesn't seem to be fully addressed.
Thus, here a refined version of the grammar for Const:

    ANGLEBRACKIRI     ::= '<' IRIRef '>'


    CURIE                ::=  PNAME_LN | PNAME_NS

    Const             ::= ANGLEBRACKIRI
                        | CURIE
                        | STRING '^^'ANGLEBRACKIRI
                        | STRING '^^' CURIE
                        | STRING LANGTAG

   PNAME_LN, cf. http://www.w3.org/TR/rdf-sparql-query/#rPNAME_LN
   PNAME_NS, cf. http://www.w3.org/TR/rdf-sparql-query/#rPNAME_NS
   LANGTAG, cf. http://www.w3.org/TR/rdf-sparql-query/#rLANGTAG

Issues: We have to think how we particularly formulate 
- we might want to resort to: http://www.w3.org/TR/rdf-sparql-query/#rString
- we have to clarify how we do address escaping, cf. [2]
