TINKERPOP-1495: Global list deduplication doesn't work in OLAP
https://issues.apache.org/jira/browse/TINKERPOP-1495
Two bugs fixed. One is simple -- `RepeatStep` wasn't adding labels to the
"emit traverser" in OLAP. One line update to `RepeatStep.RepeatEndStep`. The
other is related to some `GraphComputing` steps should behave differently if
they are being executed at master or workers. In particular, `DedupGlobalStep`.
Added two new test cases to `DedupTest` provided from the list that
demonstrates the two problems (and shows they are now solved).
VOTE +1.

added GraphComputing.atMaster(boolean) to allow steps (if the want) to know
whether they are executing locally at master or distributed across workers.
This fixes a bug in dedup() on OLAP where non-element traversers were not being
dedup'd correctly.

Fixed a bug in OLAP RepeatStep where emit().as('x') wasn't behaving
correctly. Basically, forgot to add the step labels to the emitTraverser. One
line fix. Added the complex @dkuppitz traversal DedupTest which demonstrates
that local dedup works correctly in OLAP.
