ACF QTX fields are missing translatable style

[herrvigg]

The translatable fields should display a blue vertical bar on the left to show they are dependent on the language, as for other regular fields handled by QTX.

Surprisingly this has not been reported yet, but it's been like that for years. Note this only concerns the specific ACF-qTranslate fields such as "Text (qTranslate-XT)", not the regular ones that can made translatable with the "Enable translation for standard types".

While it's obvious for the text field inputs, let's see how it can be shown for image, url, post object.
