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),
