Neo4j-2.0.0-M06

Just wanted to let you guys know that there is someone working on this. I have the server plugin up and running both through the rest API and the provided cypher indexes.

Please note:
+ I am currently building against neo4j-2.0.0-M06 using Java 1.7.
+ I haven't finished updating all of the tests yet - requiring transactions for reads is a beast of a change :)
+ Running the tests will spit out a metric ton of bbox garbage. This is due to [this](https://github.com/neo4j/graph-collections/issues/18) bug in graph-collections.
+ gremlin-groovy is no longer packaged with neo4j-server, so it is no longer marked as provided.
