- security::redirect_to_secure: add flag "-script_abort" to make it usable in filter procs (ad_script_abort triggers errors without error message) - security::get_secure_location: * align implementation to function documentation (to make it usable for sub-sites). Last version returned always the "configured secure" location, not the "current secure location" * replace regexps by util::split_location/util::join_location/
