protorpc rewrites all 40x errors to 400

[inklesspen]

Raising an exception such as endpoints.api_exceptions.NotFoundException ought to result in an error with http status code 404, but protorpc detects it as a subclass of protorpc.remote.ApplicationError and sends 400 instead.

is anyone going to fix this? makes it quite hard to debug problems before it even hits our code

ProtoRPC is not actively maintained, and was never intended to be used for this use case anyway, but I will fix it if I can figure out a way.
