Enhance Cronjob so it can also standardise Addresses

[Fabian-SYSTOPIA]

One possible future feature is that the extension will be able standardize addresses when editing contacts. An example is, if you enter the abbreviation "Teststr." in the contact edit mask, a successful Geocoding request returning "Teststraße" will autocorrect your data.

If this feature is implemented, the Cronjob should be enhanced in a way that it can standardize addresses for which a successful request has been made as well. Most likely, this would also imply that one needs additional setting for the cronjob: "standardize": yes/no; maybe also a setting "standardize all contacts": yes/no (for initial standardization).
