Sanel Zukan 1c2cfe3739 Handle case when icon wasn't selected. 
By default, 'empty' icon should be used. It is now shown in preview box and will
be selected when icon wasn't explicitly chosen. Also, redraw full desktop when icon was removed, to
prevent displaying icon which isn't available.

Added small delay when icon was removed so directory watcher skip remove event.
