Version requirements documentation for Protocol Buffers requires updates?

https://github.com/kevinweil/elephant-bird#version-compatibility: "Protocol Buffers 2.3.0, 2.4.1"

https://github.com/kevinweil/elephant-bird#protocol-buffer-and-thrift-compiler-dependencies "Elephant Bird requires Protocol Buffer compiler version 2.3 at build time, as generated classes are used internally."

It seems to require 2.4.1 when I invoke mvn package:

[INFO] Protobuf dependency version 2.4.1
[INFO] 'protoc' executable version 2.3.0

The whole dependency management in EB is a bit of a mess. EB compiles and works fine with both protobuf versions. We should make build time version configurable with a mvn flag (or just derive based on 'protoc' binary).

pull #308 supports 'protobuf.version' variables and it can be set to 2.3.0 (not sure if hadoop2 profile may not work with it. But hadoop1 profile does work).
