The new schema was generated with sqlacodegen and then manually adjusted
to fit schema/aur-schema.sql faithfully, both in the organisation of the
code and in the SQL generated by SQLAlchemy.
Initializing the database now requires the new tool aurweb.initdb.
References to aur-schema.sql have been updated and the old schema
dropped.
