Eliminate complex typed static variables
Complex typed static variables (e.g. maps) in dll-s are to avoid. On Windows they are not initialised in time (or at all) when the dll is dynamically loaded. The current use of static QHash data members results in crash on Windows when the PythonQt.dll is loaded. See details here: http://stackoverflow.com/questions/5114683/loading-dll-not-initializing-static-c-classes
