REVISION SUMMARY
  Instead of returing one long word of ';'-concatenated subjects,
  which is unwrappable return a list of strings and let the consumer handle it.
  
  This will facilitate e.g. dolphin's tooltips display of multiple subjects.
  
  - Add more subjects to test.epub

TEST PLAN
  unit test
  visual inspection in dolphin with adapted baloo-widgets
