Fix: closeOnSelect not working when item is already selected.

When closeOnSelect property is true and select item, slide menu is close. But the tapped item is already selected, this feature is not working well. Because Ext.dataview.List component does not fire 'select' event when tapped item is already selected.  

To solve this, I add 'itemtap' event handler to navigation item list to close navigation, only tapped item is selected.
