Also, fixing some indentation problems

Use proper gint8 array variable instead a string

Fixed the prototypes of MyEnhancedXkbTranslateKeyCode() and
translate_keysym() to take a gint* because those functions treat
these arguments as an int, so we get around the need to cast.

We set the hint on map, so it makes sense to check for GTK_WIDGET_MAPPED,
not GTK_WIDGET_VISIBLE as the code currently does.

The translation_domain argument should be const gchar * to allow compilation
with -Wwrite-strings. It only passes the argument to
g_option_context_add_main_entries() which is already const gchar*.
