Refactor exporter.koplugin (#8944)
Changed:
  - select multiple targets and export to them in a single click.
  - local targets (html, json and text) now are timestamped. Exporting booknotes on already exported documents will generate a new file with all the highlights present at export time. Previous files won't be deleted.

Fixed:
  - chapters are now correctly represented in html output.
  - json issues when exporting the whole history.
  - joplin and readwise crashes when they're unable to reach the server
  - joplin update notes mechanism.
  - joplin is able to recreate the notebook if the user deletes or renames its current one.
  - highlights of read-only documents are also added when exporting the whole history (affects mostly android, might affect desktop targets)
