/**
 * @brief Creates a new menu object.
 *
 * The handler function should be prototyped as:
 *
 * public <function>(menu, id, item)
 *  menu   - Menu resource identifier.
 *  id     - Client the menu is being acted upon.
 *  item   - Item the client selected.  If less than 0, the menu was 
 *           cancelled and the item is a status code.  menu_display 
 *			 should never be called immediately if the item is a status 
 *			 code, for re-entrancy reasons.
 *
 * The handler function should always return PLUGIN_HANDLED to block 
 * any old menu handlers from potentially feeding on the menu, unless 
 * that is the desired functionality.
 *
 * @param title 		Title the menu should use.
 * @param handler		Name of the handler function.  The function will be invoked 
 *						once and only once to every menu_display() call.
 * @param ml			Unused (should be 0).
 * @return				Menu resource identifier which must be destroyed via 
 *						menu_destroy().  All menus are destroyed when the plugin 
 *						unloads.
 * @error				Function name not found.
