- Introduce new proc ad_sanitize_filename implementing current best practices for ensuring a valid filename on most filesystems. - Use it in every place where filename sanitization is performed in the code and deprecate fs::remove_special_file_system_characters.
TODO deprecate also util_text_to_html? Use case of sanitizing urls and filenames might have different requirements.
- Refactor ad_get_login_url reduce replicated code and to make semantics clearer - ad_get_login_url handles now as well cases, where a subsite is mapped to an application package on a subsite - fix a bug in util_current_location in connection with hostnode map
