Change message for failing a connection to Gremlin Server #349
Merge branch 'master' of github.com:tinkerpop/tinkerpop3
removed unused images.
Properly accounted for all hosts being unavailable at Client creation #349

This change also fixed messaging to the Console which was sorta ugly as an exception is now being properly raised and trapped.
HadoopGraph is devoid of TinkerGraph embedding. Any Graph can be wrapped by a HadoopGraph. Lots of refeactoring of classes in packages to reorganize. Fixed non-bugs (stupid thing I did earlier) in XXXMapReduce in Graph sideEffect steps.
