Missing header file causes build fail

[jrklasen]

Hi, at the latest master make complains about a missing header file.

$make

You have to make and install the Google protocol buffer library (https://github.com/protocolbuffers/protobuf) and the C-language binding for the protobuf library (https://github.com/protobuf-c/protobuf-c). I just realised the README.md file hasn't been updated to indicate this. I'll update it.
