Add Selected to serialization of CGUIListBox

[chronologicaldot]

It's a very small change. CGUIListBox has a member named Selected. It'd be nice if this were serialized and deserialized, esp for the sake of scripting languages.
Thanks

Hm, I suppose it can barely count as property. Added to trunk in r6218.
Would be nice if you could give it a quick test (yeah, I checked this in untested ... I shouldn't do that).

I tested it. It works. Thank you!
Edit: I noticed there's no bounds checking, which there would be if you used setSelected(), which means some funny scrolling would happen if Selected > ItemCount. lol

Yeah, I thought about it. But in general serialize values are just read in. I could have called setSelected, but then it jumps always on serializing and not sure if that's better. Bit of "there's several options, take the simplest" solution. Can change to a setSelected call if that works better for you.

Maybe check if the attribute Selected exists and then set if it is.

The getAttributeAs functions in Irrlicht trunk generally do that now (one of the changes since 1.8). The last parameter passed in is now a default value which is set when the attribute is not found - so passing in the old variable value means stuff is only changed when the attribute doesn't exist.
