Add "Link Project and Editor Cursors" option to Windowed Editors as well

I have a multiple display setup where I can use the lower display pretty much as a “Lower Zone”. Only the true Lower Zone has a “Link Project and Editor Cursors” option however, and I’d like that to be available for independent editor windows too.

I’m showing my support with a reply on this request !
