Debugging session

Still some mismatch / leg work to achieve with memory mgmt. e.g. Output
formats are not stable yet.

- added a copy constructor for OutputFormat class (which actually might
  do the same as the one autogenerated by the compiler ? Not sure for
  the QHash duplication though)

- Copying the OF when creating a command related to the outputformats
  alteration

TODO: The app still crashes when fiddling around with OutputFormats.
Let's investigate on this.
