Added prototype click event handling on treeview nodes
Client Side

* Treeview directive
	Added node's click event broadcast.
        A first attempt using event delegation via directive attribute, has not
	been successful.
	The event was fired up to the 3rd level leaf node. On this node the event
        would not fire. Havent' been able to figure why, but I guess it has
	something to do with compilation of recursive template.
	So I switched to scope.$emit based solution.
	As of now only one treeview widget can be used on a page.
	This can be solved adding a treevidew ID and prefixing events with
	this ID.
