Putting this here so it (hopefully) doesn't get lost again.

I merged the html template changes from:

https://bitbucket.org/cmeerw/roundup/commits/8b0f049af488becd1f18ff70da
b23b9f23dd2557?at=jinja2-bootstrap

and merged bootstrap.min.css and boostrap.min.js to verison 4.1.3.
Also merged changes to templating.py.

Christof or Paul can you take it for a spin and if there are issues, 
reopen this or open a new issue.

Just pushed a few more changes for this and also updated to the latest 
bootstrap version (4.4.1).

Christof, thanks for the latest bootstrap updates.

Did you check the "Jinja template changes" section
of doc/upgrading.txt? Are the upgrading directions
still correct, does there need to be more detail?
