When a field or a model is unlinked, keep the related audit logs. Denormalize
the field and model info on the logs and log lines so that the information
is still available after the deletion of the related data model.
Also, to improve the performance of the deletion of fields and models,
add indexes on the log's model_id and log line's field_id.

- Update documentation to point to the new auditlog menu locations. These were changed because the 8.0 version was referencing menus that do not exist in 9.0
- Change version from 8.0.X.Y.Z to 9.0.1.0.0
- Make the module installable again
- Remove an unused parameter from pre-migration.py for versioning
- Fix typos and remove commented out blocks of code that were irrelevant
