Larger name change: alter xowiki::portlet (namespace, class, variable names, package parameter) to "includelet" to reduce confusion between dotlrn portlets and xowiki (xowiki can be used as an portlet in dotlrn). The change script copies e.g. the old package parameter "top_portlet" to the new parameter "top_includelet".
This change effects as well many adp files; in case of local tailorizations, please change your files as well accordingly.
