 * **************** Twinkle.addPortlet() ****************
 *
 * Adds a portlet menu to one of the navigation areas on the page.
 * This is necessarily quite a hack since skins, navigation areas, and
 * portlet menu types all work slightly different.
 *
 * Available navigation areas depend on the skin used.
 * Monobook:
 *  "column-one", outer div class "portlet", inner div class "pBody". Existing portlets: "p-cactions", "p-personal", "p-logo", "p-navigation", "p-search", "p-interaction", "p-tb", "p-coll-print_export"
 *  Special layout of p-cactions and p-personal through specialized styles.
 * Vector:
 *  "mw-panel", outer div class "portal", inner div class "body". Existing portlets/elements: "p-logo", "p-navigation", "p-interaction", "p-tb", "p-coll-print_export"
 *  "left-navigation", outer div class "vectorTabs" or "vectorMenu", inner div class "" or "menu". Existing portlets: "p-namespaces", "p-variants" (menu)
 *  "right-navigation", outer div class "vectorTabs" or "vectorMenu", inner div class "" or "menu". Existing portlets: "p-views", "p-cactions" (menu), "p-search"
 *  Special layout of p-personal portlet (part of "head") through specialized styles.
 * Modern:
 *  "mw_contentwrapper" (top nav), outer div class "portlet", inner div class "pBody". Existing portlets or elements: "p-cactions", "mw_content"
 *  "mw_portlets" (sidebar), outer div class "portlet", inner div class "pBody". Existing portlets: "p-navigation", "p-search", "p-interaction", "p-tb", "p-coll-print_export"
 *
 * @param String navigation -- id of the target navigation area (skin dependant, on vector either of "left-navigation", "right-navigation", or "mw-panel")
 * @param String id -- id of the portlet menu to create, preferably start with "p-".
 * @param String text -- name of the portlet menu to create. Visibility depends on the class used.
 * @param String type -- type of portlet. Currently only used for the vector non-sidebar portlets, pass "menu" to make this portlet a drop down menu.
 * @param Node nextnodeid -- the id of the node before which the new item should be added, should be another item in the same list, or undefined to place it at the end.
 *
 * @return Node -- the DOM node of the new item (a DIV element) or null
