Pages: various improvments: - automatic confirmation message on data post can now be avoided by using the C.POST_NO_CONFIRM flag - new tailing_slash page variable can be used to force a trailing slash at the end of the URL (by redirecting if necessary) - LiberviaPage now has a url attribute with the its relative path - new redirection methods: - getPageRedirectURL: generate and URL which will redirect to current page (or somewhere else), mainly useful for login - HTTPRedirect: stop workflow and do a HTTP redirection - redirectOrContinue: redirect a page if redirect arguments is present (usually redirect_url), else continue workflow - profile access now redirect to login page if registration is allowed.
