Update README
- Optimizes the performance of Riak value serialization -- reducing the
  serialization overhead from 9% to 2%.  The 2% is incurred YCSB's
random byte generation on the fly.
- Upgrades the Riak client to 1.1.1
- Fixes ByteArrayByteIterator#toArray
- Adds unit tests to verify the Riak columnar serialization format
- Cosmetic naming change
- Merge remote-tracking branch 'labs/master'
- Ensures that indexes are copied on update
- Extracts map merge to RiakUtils#merge
