/**
 * Add a link to one of the portlet menus on the page, including:
 *
 * p-cactions: Content actions (shown as tabs above the main content in Monobook)
 * p-personal: Personal tools (shown at the top right of the page in Monobook)
 * p-navigation: Navigation
 * p-tb: Toolbox
 *
 * This function exists for the convenience of custom JS authors.  All
 * but the first three parameters are optional, though providing at
 * least an id and a tooltip is recommended.
 *
 * By default the new link will be added to the end of the list.  To
 * add the link before a given existing item, pass the DOM node of
 * that item (easily obtained with document.getElementById()) as the
 * nextnode parameter; to add the link _after_ an existing item, pass
 * the node's nextSibling instead.
 *
 * @param String portlet -- id of the target portlet ("p-cactions", "p-personal", "p-navigation" or "p-tb")
 * @param String href -- link URL
 * @param String text -- link text (will be automatically lowercased by CSS for p-cactions in Monobook)
 * @param String id -- id of the new item, should be unique and preferably have the appropriate prefix ("ca-", "pt-", "n-" or "t-")
 * @param String tooltip -- text to show when hovering over the link, without accesskey suffix
 * @param String accesskey -- accesskey to activate this link (one character, try to avoid conflicts)
 * @param Node nextnode -- the DOM node before which the new item should be added, should be another item in the same list
 *
 * @return Node -- the DOM node of the new item (an LI element) or null
