Double click to go to a parent term

Hi everyone,

Before all, thanks for this great module. I have only one problem with it : in a block we can't go to a parent term page since when we click on the parent term, it only expend to show the childs terms.

I propose to modify the module so that we can go to the parent term page if we double click on it, and expend/collapse the childs terms if we single click. This is the way DHTML menu module works, and I think this is an interesting way to manage it.

What do you think?
