remove all taurusdesigner widget parametrization to avoid issues between qt versions. Those parametrizations are now in the python gui code.
Also, as the signals doesn't work the same way in PyQt4.4.3, where this has to work, implement my own qt signalling class.
As numpy 1.3.0 hasn't yet the iterators, and has to work with this release, implement something equivalent (but probably less efficient).
When file process finish, log the time needed.
Even the issues with old Qwt5, prepare it for backward compatibility improve.
