Wine .exe and other executable thumbnailer for Gnome

 gnome-exe-thumbnailer is a thumbnailer for Gnome that will give Windows .exe
 files an icon based on their embedded icon and a generic "Wine program" icon.
 If the program has normal execute permissions, then the standard embedded icon
 will be shown. This thumbnailer will also give a thumbnail icon for .jar, .py,
 and similar executable programs.
