Serializers for Guava predicates

[shevek]

Most of the builtin Predicates in guava's Predicates.java implement Serializable but are not serializable by Kryo by default. Please can there be a utility class which registers these as a block, e.g. Predicates.containsPattern(String).getClass(), etc.

Do you want to submit a pull request? I can make the release then.

Given the code in #26, one can do kryo.register(Predicates.containsPattern("foo").getClass(), new SerializableSerializer<Predicate<CharSequence>>());

[shevek]

Actually, beyond that, it would be useful to have a set of recipe classes, so that e.g. GuavaSerializers.register(kryo) or JdkSerializers.register(kryo) could apply all recipes relevant to a given environment or dependency library which one might be using.

Closed bsaed on closure of #26
