Fixing the attribute for contextmenu plugin.

[Jacquelin]

This allows the use of all settings (ie : select_node and show_at_node) The attribute tree-contextmenuaction becomes obsolete BUT users can use a Ojbect of Function on items (like in jsTree)

example :

<js-tree tree-plugins="contextmenu" tree-contextmenu="contextMenu" />

$scope.contextMenu = {
    items: {
      "Node": {
        "label" : "Node",
         "action" : function(obj) { 
          alert('node')
        }
      }
    }
  };

Here is a plunker (I reuse the same idea of #10 ) http://plnkr.co/edit/qr8vittbOwvRkNrtQyjz?p=preview

PS : I make this PullRequest to use select_node option. I would understand if it's not merged.

Thanks to you !!

Just a question, should you not update the demo page ? Do you need help ?
