protobuf 1.4.2

Ruby implementation for Protocol Buffers. Works with other protobuf rpc implementations (e.g. Java, Python, C++). This gem has diverged from https://github.com/macks/ruby-protobuf. All credit for serialization and rprotoc work most certainly goes to the original authors. All RPC implementation code (client/server/service) was written and is maintained by this author. Attempts to reconcile the original codebase with the current RPC implementation went unsuccessful.
