Message on empty list

I added some code to display a message when the list is empty. I thought this might be useful and was wondering why you guys didn't do this already

New Options
---------------
   
    * **showEmptyMessage** _(Boolean, default: true)_  
    If true, a message is displayed if the filtered list has no items.

    * **emptyMessageClass** _(String, default: "list-empty-message")_  
    What is the class for the empty message?

    * **emptyMessageText** _(String, default: "No Items Found")_  
    The Message to be shown when the list is empty.
