New build almost ready, great performance enhancements

Quick update, we are now preparing the next build. We are quite excited since we finally finished implementing several optimization that where missing on the mapping manipulation algorithm. The use of "OR" in WHERE clauses is much more robust now and we now are able to exploit FOREIGN KEY contraints.

The result is that in virtual RDF Graph mode, with real databases and usual SPARQL queries we rarely generate more than 1 query SQL query one which often matches what you would have written yourself in SQL. An it is FAST (also for more complex SPARQL with variables everywhere, even if its more than one query), even with inference enabled.

We'll be posting benchmark numbers soon. Stay tunned!
