Issue #154: Make `Cursor hand` a cursor with hand shape ...as the name suggest, not plain arrow. The consequence is that uite a few widgets (buttons, nost notably) now show hand cursor rather than plain arrow. This makes Smalltalk/X UI consistent w.r.t running on X11 but may not be in line with Windows UI design guidelines. This has to checked and properly fixed in individual widgets - not by making hand cursor actually an arrow!
