aui LoadPerspective with a new window

[Riccardo Cohen]

Thanks a lot for that piece of code. I'll try this way. But I think that 
one little patch could be applied : after LoadPerspective, it should be 
easy to check if some pane are not visible (ideally also not in screen), 
and build a new paneinfo for these.

I tried to do that, but I could not find the way of checking if a pane 
is visible...
