Merge branch 'OSX_merge_cleaned'
This merge: - fixes issues with invalid mutex - moves tests to Python 3 - allows to compile the code natively under Visual Studio with CMake - allows to compile under QtCreator under MS Windows - fixes some issues with test suite - allows to run tests under Windows - allows to compile using QMake (and easy adding to Qt projects) - decreases delays between sending commands thus increasing 2x communication speed
