Refactoring: OutputList & OutputGen

- Initialized member variables inside the class
- Added copy & assign operators for OutputGenerator and Derived classes.
- throw a runtime exception when OutputGenerator is copied while is file
  is still in progress.
- Added clone method to make a copy of OutputList.
- Moved the implementation of enable() & disable() and friend into
  OutputGen instead of having the same implementation in each derived
  class.
- Made m_dir and m_fileName readonly (members dir() and fileName())
- Removed call to new while adding generators to OutputList
- Replaced QStack by std::stack for the "enabled" state.
