Release 1.4.2:
-This version just has a small addition where the second audio check does not happen if there are 5 lines or less, for less friction on some videos, mostly older ones. Five is the minimum number of lines possible in the Settings menu in the current YouTube UI, and auto-dubbing should not be possible in this situation.

-Next release should check more precisely to see if there's an audio track option at all before running the second check, but I want to make sure this works thoroughly first as that one may have a higher fail rate.

Double enforcement mechanism added to stop YouTube reversion bug.

Localization added for:
Spanish
German
French (including Canadian)
Portuguese (European and Brazilian should both work)
Italian
Bahasa Indonesian

Also, fixed an issue where it sometimes left the settings menu open.

I'll add automatic general localization in the future, and may changed the icon.
