Move "Deactivate/Activate all" to top of list

Description

When choosing which objects to show there's a long list of objects to choose from, and at the very end there's the options "Deactivate all" and "Activate all". Good options to have, but only if you know they're available. And having them at the very end of that long list makes them very easy to overlook. I think it would be much better to have them at the top instead, so they're discoverable by everyone.

Thanks!
