FairMQ Examples cleanup

- Rename Tutorial3 MQ files for uniform naming.
  - Add search for dylib in FindDDS.cmake (OSX).
  - Add more detail to the DDS example readme.
  - MQ Example 3 (DDS): choose network interface via command line option.
  - Give FairMQ examples their own CMakeLists.txt for clarity.
  - Remove C++11 checks in Tutorial3 from the code (they are now in CMake).
  - Add Serializer for device properties (FairMQDevice::ListProperties()).
