Add scene-name info into undo list.

[tatt61880]

Current undo list just say "Undo load scene".
== Suggestion ==
1. Add scene title to the info. i.e. "Undo load scene: Tower", etc.
(NOTE: Loooong titles can be shorten ": abcdefghijklmnopqrstuvwxyzABCD...")
2. Add re-load mark to buttons to load scene.

1. good idea (should also be put at redo menu; reload scene:"")
2. bad idea (not clear that it reloads the scene, especially in an undo-menu)

Oops, I've misunderstood. "Undo load scene" won't reload the scene, at all. So I reject 2. by myself.
Thanks, monstertje3.
