Code review comment for lp:~widelands-dev/widelands/critter_editor_categories

@GunChleoc: while the code may be old, it is fact that in latest version (8236) the disturbing text does not show in the Animals menu, so we must assume this branch is responsible for its appearance. Can you agree with that? I have seen the text goes away when any item is selected, but I still hold it is preferable to deactivate the text in Animals until a better solution for this aid is found.
