[GUI] Add prefs for translators

Browse Source 
When creating the original list of locales available to FreeCAD, also
scan the external directories and add those entries to the list of
locales. This enables the installation of a language pack in an
already-installed version of FreeCAD, allowing translators to test their
work more easily.

Add a hidden preference that will allow translators to add an entirely new
language to FreeCAD via user preferences, without requiring modification
of the FreeCAD source code.

Add a hidden preference for an additional translation directory.
