Purpose: -------- This commit removes the "hideKanbanOption" from the properties field. This option allowed to prevent users to make properties visible on cards (kanban cards and calendar popovers). The rationale being that there is no reason to prevent users of adding properties on cards now that they have been redesigned (see commit [1]).
