New menu builder implementation merged from branch menustructure to branch 1,.4.x
because new UI implementation requires new translation keys and there is a big risk that the
translations diverges from what we need, after discussion with Felix and Marcel I merged branch
menustructure to branch 1.4.x .
Because currently ribbons do not work there I disabled them on branch 1.4.x .
I suggest that Marcel continues to work on Ribbons on branch menustructure where the ribbons remain
enabled so that he can develop and test.
