home page is is now accessible

Had to allow access to a function(categories/get_categories_and_latest_post) represented by a
requestAction method in latest_post element used in the the home.ctp
layout that is in turn being used by the  home.ctp view. The restricted method being called by the element within the home layout also restricts the home url as a whole even if the home action was explicitly allowed via the Auth Component's allow method.
