[TYPO3-v4] Hide icon in listview in 4.4 has change

[Benjamin Mack]

Hey Patrick,

yup. this was a major Usability change, because before there was
inconsistency in this feature ("the icon for the hidden state"). As you
might have known, there are icons that identify actions, and then you
have icons that identify states. Hide mixes both variants, in the list
module and in other modules.
We had some tests with Usability experts and that was literally the
first thing they noticed in the backend.

All the best,
Benni.
