Project Idea: Make bleach work with new version of sanitizer

See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=844943 for details. A new version of html5lib was uploaded without checking if every package depending on it will work with the new version. Some functions were removed in the new version so it does not work now. We have have to modify bleach so it uses new functions from html5lib. This is in python. Reply if you are interested. We need to fix this to upload pagure, which is another software similar to gitlab. There was a discussion on updating debian's git hosting and community selected pagure over gitlab because some features of gitlab is available only on Gitlab Enterprise edition.
