Batch Values 1.1.1

• A run that adds or changes a link now asks the Inverse Properties module to keep the other side
  of it, as Omeka's own item form does (inverse_properties_set_inverses). Before, a link added by
  a run (to "Related item", say) had no link back until somebody saved the item in the form. Without
  that module installed nothing changes.
• And before that module looks, the records linked read their values again: a run that saves one
  item twice (one entry per value added) made the link back twice, since the module looks at what
  Doctrine holds in memory.
