Redeployment on Dokku with imported database backup fails

A clean development instance, based on the last code version of scriptum (Budapest release) is to be deployed and access given to @mladen and Katya, Daria and Thies.

Unfortunately the database dump from the old instance will have the database name and user name hardcoded, which needs to be changed according to the new configuration, i.e. with sed -i, before importing it in to the new database.
