Windows specific function for migrating from LibGlade to GtkBuilder

Glade had a gtk.glade.bindtextdomain() function to define the directory

where to look for translations (.mo-files). It is now replaced with call

to locale.bindtextdomain() which exposes the C librarys gettext

As MS Standard Runtime C library have not such interface call to

Python's locale.bindtextdomain() is not supported on Windows systems.
