Multi Output Support

Now you can create multiple export targets with different queries, different settings.

Instead of a draft field, I introduced a published field as it felt more convenient:
When you draft a note, it's easy to forget to add an extra field to make it a draft.

Added nice debug stats in the indicators:

• bug icon, if the script removed links, or could not find attachments
• all the links that are in the file, external, internal
• all the internal links and attachments and what and where the files went

Wrote some unit tests, to make sure

• all the links are found and replaced properly and
• old settings are imported properly.
