Fix some issues related to Netflix readings

[killergerbah]

• If multiple Netflix readings appear in same subtitle, their offsets should render correctly now. Tested with "無為‎転変" in the attached file.
• If colorization is disabled, then returning token text as-is from applyTokenStyle. Without this, words with Netflix readings show up with the error style.

Yeah I was originally worried about the regex replacement and using the offsets, as I wasn't sure if it should be right to left or be offset.

I realize the really issue is that applyTokenStyle() has been decoupled from SubtitleColoring so it can be called when dictionaryTrackEnabled() is false. Checking that should be the only thing that's needed as token.status shouldn't be undefined even if just using readings and frequencies.
