Multiple object properties

Remember this gem from the original blender 2.5 design paper? This was never implemented for some reason... I think it should. Especially now, that we can go to Edit mode on multiple objects at once. Such properties would be far more intuitive and would save time on complex scenes.

To quote the paper: "Multi-object editing can make complex projects manageable again."

Though, I think there should still be a checkbox on the header to either see properties of the active object, or all selected objects.

I know you can edit properties of multiple objects by holding "Alt", but that it very non-intuitive, hard to find, and lacks visual feedback.
