filter the doPlot() to avoid unnecessary replots when nothing has changed

split out the signalling descriptions to a separated file to even more isolate the unique change place on their description and configuration

first approach to introduce the Beam Current as a user variable, modifiable in the facade's fits dialog. But it's not a good solution because it forces the user to get into the fit adjustments when it shall only be opened when there are missing fits in facades.

moved the setting of the beam current to the loader dialog (this make it a constant value) where it has more significance

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.
