[Neo] verbosequadstore loading

There are some problems at the moment regarding insertion speeds.

o We haven't yet created an rdf store which can use a BatchInserter (which
could also be tweaked to ignore checking if statements already exists before
it adds each statement and all that).
o The other one is that the sail layer on top of the neo4j-rdf component
contains functionality which allows a thread to have more than one running
transaction at the same time. This was added due to some users requirements,
but slows it down by a factor 2 or something (not sure about this).

I would like to see both these issues resolved soon, and when they are fixed
insertion speeds will be quite nice!
