Feature request: Isolate

[KrisBee]

So in 3ds Max there is a feature called "isolate" that allows you to temporarily hide all non selected objects in the scene and then bring them back when you end isolation.

I think this would be a really handy addition to Wings. The current hide / unhide has the flaw that it will turn objects that you want to stay hidden visible when you use "unhide all objects".

If you're like me, with hundreds of objects in the scene, it becomes a pain to manually hide things every time after you've used hide/unhide.
