Update translation to Danish, Norwegian, Finnish and Spanish (CLI)

[matsduf]

For Zonemaster-CLI there are two messages to be translated to Danish, Norwegian, Finnish and Spanish. You can provide the translations as comments to this issue.

There is a new option --hints to provide a private root zone for Zonemaster. Provide translation for:

Name of a root hints file to override the defaults.

There is a new error message when more than one domain name is provided on the command line. Provide translation for:

Only one domain can be given for testing. Did you forget to prepend an option with '--<OPTION>'?

Done:

• Danish
• Norwegian
• Finnish
• Spanish
