update to xowiki 0.33: direct inclusion of xowiki pages via {{en:mypage}}, simpler default pages (see xowiki/www/default-pages), obsolete files removed, fixed bug when a new xowiki instance is created
upgrade to version 0.27. alignment with xotcl-core 0.38 (use cr_item.name instead of cr_revisions.title), change page_title to title (potential incompatibility) to rely more strictly to the CR data model (most files are effected).
