Made Tinkerpop libraries external, added Pipes and Gremlin as well.
Continued improvements to the IndexDatabase and DocumentScanner to improve performance and reliability.
Addition of .toItemFriendly to ensure we correctly convert to Item-writable values
Safety check on DocumentCollectionIterator to avoid long-running error loops
Improvement in DominoReference and DominoReferenceCache to force re-wrap of queued References. If a reference was pulled from the cache after it was queued, it drops its lotus object pointer so that it won't recycle it.
