Translations:Release notes 014/8/en

With the many complications caused by the double-license model of FreeCAD (LGPL & GPL), some of the components of FreeCAD (namely the OpenCasCade kernel) being incompatible with GPL code, we decided to switch all the remaining bits of GPL code of FreeCAD to LGPL. As a result of this operation, PyQt is not used anymore, and has been replaced by PySide. There is not much consequence for python scriptwriters, PyQt can still be used inside FreeCAD.
