So, these classes like Integer and langBoolean exist solely for

streaming to our java server, so let's just make them streamable directly.
Does away with the need for custom Streamers.
Also made them Hashable, in case we read a StreamableHashMap containing
Integers as keys, for example.
Less code is better code.
(Why was BooleanStreamer added the other day? langBoolean was already Streamable
 and was already in Translations)
