Erroneous Double Entries

In some cases Greek text exists under two separate headings. One of the texts should be removed (otherwise searches will return misleading results). See also #82.

• p.fouad.pg186-inv69427 = sb.18.13872
  • remove the text at p.fouad.pg186-inv69427 and add sb.18.13872 to reprIn information - add reprFrom info to p.fouad.pg186-inv69427 in sb.18.13872
• p.mil.2.24 = sb.8.9927
  • collate and remove one of the text versions and follow what HGV does (to be applied as a general rule)
• p.vat.aphrod.10.xml = p.mich.aphrod.1.xml
  • collate and remove one of the text versions - not entirely sure about this - p.vat.aphrod.10 is only part of the text, the Greek text should, however, be deleted, I reckon, and a redirect to p.mich.aphrod.1 should be added
• The same texts are to be found under p.eirene and p.vind.eirene !!!!
  • I reckon the whole p.vind.eirene files should be deleted - it is there that false ddb identifiers are to be found (e.g. p.vind.eirene.1.10.xml in the TEI header section: <TEI.2 id="p.vind.eirene.1.10" n=";1;10">)
