Add (optional) Google Protocol Buffers support (example in Tutorial 3).

To use protobuf, run cmake as follows: cmake -DUSE_PROTOBUF=1 .. For this, protobuf library has to be installed on the system. Further changes: Clean up splitter/merger: default are N-to-1-merger and 1-to-N-splitter. Fix bug in nanomsg message deallocation. Setup proper buffer sizes for nanomsg/zeromq via cmake/bash script. chmod +x for start scripts.
