Trying to sort out configurations as we got into a bit of a mess on 
Expo in the last couple of weeks with two (notionally identical Debian 
Bullseye) expo laptops Crowley (which has local troggle installed and 
can run locally) and Aziraphale (has local copy of troggle repo but is 
not configured to run locally), Martin Green's laptop (Ubuntu 22.04.2), 
Philip's Barbie laptop Ubuntu 22.04.3). And of course the server itself 
expo.survex.com which is running Debian Bullseye. But most development 
recently had been done on Philip's two other machines, desktop and PC, 
both running Ubuntu on WSL on Windows and both using venv environments, 
which Crowley also does.

- settings.py 
is common to all configurations, 
but these are all different:
- localsettings.py
- requirements.txt
