 * checkMenu - checks to see if the specified <menupopup> contains the
 * expected items and state.
 * expectedItems is a array of (1) item IDs and (2) a boolean specifying if
 * the item is enabled or not (or null to ignore it). Submenus can be checked
 * by providing a nested array entry after the expected <menu> ID.
 * For example: ["blah", true,              // item enabled
 *               "submenu", null,           // submenu
 *                   ["sub1", true,         // submenu contents
 *                    "sub2", false], null, // submenu contents
 *               "lol", false]              // item disabled
