			Variable: context_menu_item
			*object* Used to construct a context menu entry, this structure will always be a part of an object.

				separator_before - *boolean* should there be a separator before the item. Default is _false_.
				separator_after - *boolean* should there be a separator after the item. Default is _false_.
				icon - *string* if supplied this string is used for an icon, if it contains _/_ it is treated as file, otherwise it is applied as a class on an INS object.
				label - *string* the text for this item
				submenu - *object* if supplied this object is used to build a submenu. It should consist of keys, each of which is a <context_menu_item>.
				_class - *string* if supplied this class is applied to the LI node.
				_disabled - *boolean* is this item disabled.
				action - *functon* if supplied it will be executed when this item is clicked / activated. If not supplied or the function returns _false_ the contextmenu won't be hidden after execution. To force a context use _$.proxy_.
				In the function you will receive a single argument which is an object, consisting of four keys:
				_item_ (the <context_menu_item> object),
				_reference_ (the DOM node used when <$.vakata.context.show> was called),
				_element_ (the DOM node of the context menu),
				_position_ (an object consisting of _x_ and _y_ keys, represinting the current position of the menu)

			Parameters:

				data - the additional object to pass along with the event. By default _data.inst_ will be the current instance, so when you bind to the event, you can access the instance easily.
