Title: Updated Kryo to version 2.20

sbt/sbt test pass.

Tried it on Shark using a join query that produces 60 million rows and it worked fine. Saw a negligible performance increase in the join query (very hard to tell the difference - if anything, ~ 5% - could well be just system variability even though I tested 20 times).
