New description:

 As part of the effort of porting to python 3, moving the web code away
 from nevow is the simplest option, since nevow won't be updated (and the
 code is using old parts of nevow anyway) but twisted.web is already
 compatible with python 3. twisted.web.template already does most of what
 the templates used in nevow in the first place.

 Since nevow and twisted.web interoperate enough, this port can be done
 piecemeal at the granularity of one template per ticket/PR.

 These were formerly part of the web UI, but they are no longer in use, and
 so probably not relevant to porting:
