Added Transaction support with Transaction.begin and Transaction.run
Wrote basic specs for Transaction.begin and Transaction.run
Added PlaceboTransaction to encompass common behavior between rest transaction and embedded transaction
Removed run_transaction from embedded session
Added begin_tx to rest and embedded session
Removed the jars
Updated Travis script to install Neo4J 2.0.0 stable release which now happens by default
Made all rake test task names plural to reflect that we’re testing nodes and relationships instead of a node and a relationship - weird I know!
