[jQuery] [Treeview] Cookie based persistence
For those using the treeview plug-in by bassistance.de, note that for
the cookie based persistence to work you must include the jquery
cookie plugin which can be found here.

This may be written somewhere in the original documentation, I'm not
entirely sure so I figured I might as well post it for those who are
struggling with it like I was.
Have fun with this great plug-in.
