Some temporary backwards compatible bits for extant Corpse Craft clients.

Narya's strict approach to over the wire compatibility is not so nice when you
have cross-language clients that can't be updated at the same time as the
server.

Maybe we should consider a new over-the-wire format for C++ clients that is
more like pbuffers, which the Narya server could translate to and from Java
Streamable instances, and the C++ side could either use pbuffers directly or
have a similarly change resilient I/O layer that turned over-the-wire data into
C++ objects that mirrored (a potentially out of date) version of their Java
counterparts.
