Title: Serialization fixes

This does three things:

1) Moves serialization to a new package: scalding.serialization
2) Doesn't use Kryo for writing classes in collections (most questionable, but we are seeing some issues with unregistered classes).
3) Make sure to flush after each object write in collections (important to avoid bloating the intermediate buffers).
