[francesco fantoni <francesco@xxxxxxxxxxxxxxxxxxxx>]

I'm refining a bit this undo stuff:
I've added more events to Undo system (adding a clip to track, adding a
new track, track renaming, and so on).
I have added a Tree-view panel as well for history on main window, it
could get useful to implement a "go directly back to that stage"
function clicking on it.

cheers,
francesco
