translate (or add the manual option to extract in order to translate) embedded subs
Translate requires the sub to be translated, to be external. Sometimes it's there, just embedded (e.g. as ASS).
Current implementation of Embedded Subs Extraction is only global, not per show.
1) allow for translation of embedded subs (which would first extract them and then translate them and then delete the extracted in case the language profile does not require them)
2) have a button for manually extracted the embedded subs (per episode or per show selecting episodes, the way Tools appear) ; which would the user follow with translation action.
