Add some notes about expected state of Gremlin Console #354
Add fix and test for plugin loading in sessions for Gremlin Server.
Fix code examples for GraphStrategy #357
added gremlin-dashboard image.
Add docs for graph Feature  #317
Merge branch 'master' of github.com:tinkerpop/tinkerpop3
Update the number of suites

Stinks that this is hardcoded, but there's no dependency on gremlin-tests here to know the number of available tests.
Correct docs in example around describeGraph.
Turn on a couple extra tests around strategy wrapping.
Uncommented VertexProgram.getMessageCombiner(). TraversalVertexProgram now makes use of TraverserSet messages to allow for combining when messages to a vertex are not necessarily to the vertex, but also to its edges,properties,etc. Uncommented TinkerGraphComputer's message combiner usage. Added GiraphMessageCombiner to wrap a TP3 message combiner appropriately. MessageType.Local only supports M->M. No more M1->M2 as edge modulation should not change the message class, only modulate it.
removed 'deep reference' feature in GraphComputer/VertexProgram.
renamed MessageType to MessageScope. Added VertexProgram.getMessageScopes(). Tweaked up PageRankVertexProgram and PeerPressureVertexProgram to get edge counts via message passing. Fixed a edgeFunction bug in GiraphGraphComputer. Fixed up StringFactory for VertexProgram and MapReducers that don't have an internalString.
