TINKERPOP-1451 TinkerGraph persistence cannot handle a single file name as
the graph location
https://issues.apache.org/jira/browse/TINKERPOP-1451
This is all good now:

org.apache.commons.configuration.BaseConfiguration()

gremlin>
configuration.setProperty(TinkerGraph.GREMLIN_TINKERGRAPH_GRAPH_LOCATION,
'test4.gryo')
==>null
gremlin> configuration.setProperty(Graph.GRAPH, TinkerGraph.class.getName())
==>null
gremlin>
configuration.setProperty(TinkerGraph.GREMLIN_TINKERGRAPH_GRAPH_FORMAT, 'gryo')
==>null
gremlin> graph = TinkerGraph.open(configuration)
==>tinkergraph[vertices:0 edges:0]
gremlin> v = graph.addVertex('Person')
==>v[0]
gremlin> v.property(list, 'age', 1)
==>vp[age->1]

TinkerGraph's would not save on close()
if the path was just a file name. Tested "just a file name" manually and
added a test for relative paths - didn't want to generate test data outside of
our test directories. TINKERPOP-1451

Added a test for persisting multi-properties in TinkerGraph
Changed the test back to using a relative path in the data directory -
didn't like it polluting the source control directories.
