A *partial* backport of 0.4.14-dev-1506-g c82ba3485e , part of (#2603)
That menu item never had any effect up to now as it had no implementation in ros,
and it also does not exist on Windows at this location.
The desired effect can already be achieved by just hitting F5 or selecting "Refresh" from the same root-context menu.
I do port back only the removal of this commit for now, and not the added new functionality in the submenu "Arrange Icons By", to
allow translations for that to settle down a bit on master.
