Updates description?

• Add benchmarks for measure the performance of the library and individual components
• Small fix in the logging (SpaceProto.cpp, crashed when no session_.user)
• Disable logging of WebSocketsPP library by default (need to set config.enable_tracing_ for enable, please let me know if you think that there should be separate option)
• Fix finding test data files in the resolveTestDataFile()

Currently some multi-threaded tests are disabled due exist some issues with concurrency (I will have a look to them later).

Please let me know if you think that need to remove some existing benchmarks that implemented as unit tests.
