Added historylog cleanup to "daily db maintenance"

The sql table "historylog" contains information about every create/update/delete done in a database. This table is used for contentstore replicaitons.

The problem with this data is that it is never removed and fills up the database after some time (years).

We now added a cleanup task to the "daily maintenance" procedure. This removes all entries older then 3 month. Because this data is used in contentstore replications you have to use "full compare mode", if a replication stopped for more then 3 month.

In addition we removed some unnecessary log-entries that are not used by the system:

  • log entries for creation of file derivates
  • log entries for updates of db extension data
