 Bug 7683: Cataloguing statistics wizard improvements

- Add 3 options for cells value
  - Titles count "COUNT (biblionumber)"
  - Items count "COUNT (itemnumber)" (current behavior)
  - Deleted items count "COUNT (deleteditems.itemnumber)"

- Add to selectable rows, colums and filters:
  - items.notforloan
  - items.materials

  For each of these fields, retrieve the label in the default cataloging
  framework.
  If no MARC field is mapped to the field in question, it does not show
  this line in the wizard.
  If the MARC field is associated with a list of authorized values, it
  displays a dropdown list for the filter, otherwise it displays a text
  field.

- Add to selectable rows, columns and filters:
  - items.dateaccessioned (creation date)
  - deleteditems.timestamp (deletion date) (Only if the third option (eg
    count deleted items) is selected)

- Add unit tests for GetMarcSubfieldStructureFromKohaField
