Add database schema versioning (#1688)

Browse Source 
## Issue Addressed

Closes #673

## Proposed Changes

Store a schema version in the database so that future releases can check they're running against a compatible database version. This would also enable automatic migration on breaking database changes, but that's left as future work.

The database config is also stored in the database so that the `slots_per_restore_point` value can be checked for consistency, which closes #673
