Various cleanup in i18n code (having funcs implemented in two different places is tricky, you quickly forget to add/edit one, we already have this problem with ugly bplayer stub... e.g. since r53938, BLF_locale_explode was not implemented in non-WITH_INTERNATIONAL builds). Also tried to simplify #ifdef's here...
