[gnome-shell/workspace-thumbnails: 4/13] Don't check for Workspaces.WindowClone for window drops

[Owen Taylor <otaylor src gnome org>]

commit ff74078e2c8ae4a5ce2880e428aa5d1183c952f5

    Don't check for Workspaces.WindowClone for window drops
    
    When checking the type of a DND source, instead of checking
    'instanceof Workspaces.WindowClone' accept any actor with realWindow
    and metaWindow properties. This will be useful to support a separate
    type of actor dragged from workspace thumbnails.
