[Tracker] should change symlink icons on the fly

[diver]

Start Terminal and type:

open .
mkdir folder
ln -s folder symlink_to_folder
mv folder renamed_folder
(close home folder)
open .
(note that symlink_to_folder changed it's icon)
mv renamed_folder folder
(close home folder)
open .
(note that symlink_to_folder changed it's icon again)
