Reorganization of the QA (Rec), by splitting a MTR and MCH parts, so they can be used separately if the need arise, and anyway be more easy to develop and maintain in parallel.

Also, according to last DAQ meeting discussions (http://indico.cern.ch/conferenceDisplay.py?confId=70835), a few changes in our QAs are implemented :

MCH :

- can now cut on low buspatch occupancies (if the config could be retrieved)

MTR :
- Implementation of raw data checker and update of shifter information (we check trigger algorithm errors, errors in the raw structure, and dead channels/boards).
- General clean-up of QA histograms.
- Improvement of graphical results.

Few more changes still to come...
