Background selection offers any object [EDITOR] [BUG]

[Nepster]

I just tried what happens if you click on the button "Select background". And it turns out that it opens the object selection window, offering any and all of the object pieces. But I am fairly sure, that I don't want to have the exit sprite as a background.
So please only offer the actually valid backgrounds in this selection window.

That'll require some tricky changes as long as backgrounds are still stored in the graphic sets as objects.

However, it won't actually let you choose one that isn't a background. A similar result happens when trying to place a background image as a regular object.
