winemac: Better handle z-ordering windows that are in Cocoa parent-child window relationships.
The code had been handling ordering sibling windows relative to each other, including windows neither of which were child windows. However, it wasn't properly handling other relationships (e.g. cousins, nieces, uncles, etc.).
The reason this is complicated is that Cocoa keeps child windows in a fixed relative order to their parent and siblings. The normal -orderWindow:relativeTo: method doesn't work. One has to remove the children from the parent and re-add them in the desired order.
