2.06.3:schwarherz:18 Validation/cleanup

working on validating title history. All the non-existent character
title holders have been fixed, a couple "isn't alive when receives
holding" errors were fixed. Removed comment reference to "Antipapes" in
favor of "Antipopes". Began the process of merging the Strategium
character file into our own files.  Added localization for the Book of
the Dead. Added localization for the Icelandic conversion decision.
