cWindow and cWindowOwner

[FakeTruth]

I'm not yet sure how the cWindow class works. And how does cWindowOwner fit in?
From what I've seen, cWindowOwner has descendants although they don't really use much of it - there's no virtual members, so there's not much to override.

Also, does the current windowing work multi-player? (both players open the same entity's window, one player puts something in it, does the other player see it?)

The whole idea of the cWindowOwner class is that it opens a single window for multiple players. a cChestEntity is a cWindowOwner, because it owns a window.

I'd say this is a good candidate for a rewrite, or at least for a very good documentation

Perhaps, I don't really understand it much myself, other than that it works XD
