TINKERPOP-1508: Add choose(predicate,trueTraversal)
https://issues.apache.org/jira/browse/TINKERPOP-1508
Added `GraphTraversal.choose(predicate,traversal)` and
`GraphTraversal.choose(traversal,traversal)`. These are implemented as
`choose(traversal,identity())`. Up to this point, `choose()` has been
if/then/else-semantics and now with addition, we have if/then-semantics.

added choose(predicate,traversal) which is a map to
choose(predicate,traversal,identity()) and gives us if/then-semantics instead
of always requiring if/then/else-semantics.
