[feature request] put last status for an entry as custom field, to be able to show that as column

[Saibaschbeis]

Currently, the HIBP check - as far as I can see - is a simple "on demand check".
However it would be benefical to have the last check result for each entry saved to that entry as a custom field (string).
This would also enable to show that field as a column in KeePass, therefore having a fast overview if any entry is compromised.
This feature could also be made optional (default "off"), if users don't want entries to be modified.
