- now that we have to configure usher's configuration file anyway,

we can skip the explicit configuration of its host and admin
  password, as we can directly read that from the configuration file
  itself
- expand the SyncMonotone plugin a bit to where this actually becomes
  useful, i.e.  create an accompanying key for each created database
  and also add some initial database-specific configuration
- update the config docs in idf.php-dist to reflect the changes and
  add more details about the inner workings of the SyncMonotone plugin
