Manage departments, databases.

Each departement `X` has its own database, `SCOX`
|
|
and a small configuration file `.../config/depts/X.cfg`
|
|
containing the database URI
|
|
Old ScoDoc7 installs config files contained `dbname=SCOX`
|
|
which translates as
|
|
"postgresql://<user>@localhost:5432/<dbname>"
|
|
<user> being given by `SCODOC7_SQL_USER` env variable.
