Title: Adds UUIDSerializer to ext

Just a simple serialization extension for UUID. I noticed this one wasn't there and some people (like me) need it.

I'm not sure if there should be other extended formats like java.sql.Date, but I named the file JavaTypesSerializers.scala proactively. A strategic rename is left as an exercise to the reader.
