Subject: [PATCH] App: Add the definition of the text domain

This adds the definition of the text domain used by gettext to
translate the strings of the user interface. gettext will search for
a package named "fractal" in the directory "./fractal-gtk/po". Thus
MO files containing the translations must be found in
"./fractal-gtk/po/[LANG]/LC_MESSAGES/fractal.mo".
