C3PO saves only partial information about conflicts #59

For the following identification conflict (taken from FITS output)

<identification status="CONFLICT">
    <identity format="Extensible Markup Language" mimetype="text/xml" toolname="FITS" toolversion="0.6.0">
      <tool toolname="Jhove" toolversion="1.5" />
      <tool toolname="OIS XML Metadata" toolversion="0.2" />
      <version toolname="Jhove" toolversion="1.5">1.0</version>
    </identity>
    <identity format="XMP" mimetype="text/xml" toolname="FITS" toolversion="0.6.0">
      <tool toolname="Exiftool" toolversion="7.74" />
    </identity>
  </identification>

C3PO will store this value:

"format" : { "values" : [ "Extensible Markup Language", "XMP" ], "sources" : [ "0", "2" ], "status" : "CONFLICT" }"

This means that C3PO saves only a first tool reporting a property value in a conflicting situation. This needs to be fixed.

To resolve this issue the data model should be changed, as well as all map reduce queries.
