auto_translate have some problems

[vmjcv]

in LocalizationAutoTranslate._on_translate_pressed(). the _from_code = _from_code.to_lower()
but in LoclizationData.translation_by_locale(key, locale). the translation.locale is not to_lower().

so if the local is zh_CN.
translation.locale = zh_CN
locale = zh_cn

translation.locale!=locale

maybe you need change it like this

func translation_by_locale(key, locale):
	for translation in key.translations:
		if translation.locale.to_lower() == locale:
			return translation 
	return null
