Ubuntu 11.10's minor but relevant icon change

Although there won't be a new icon theme in Ubuntu 11.10 (it will probably land in Ubuntu 12.04), a number of relevant icons has been changed during this development cycle.

A new update in the Ubuntu Mono icons has brought a new interesting desktop/user-desktop icon, represented by the default wallpaper with a top white-ish line, basically a miniature of the desktop with a panel.
