[06/50] tinkerpop git commit: TINKERPOP-1878 sparql() step works over
remoting
TINKERPOP-1878 sparql() step works over remoting
At this point it is only tested to work with Gryo 3.0. Fixed a bug with how dynamic gryo registrations work - they failed if you didn't have a specific serializer specified. Introduced a bit of a hack to make SparqlTraversalSource behave like a GraphTraversalSource and thus more cleanly follow the DSL pattern. Not sure if that's a great approach yet or not, but it seems harmless at this point.
