Metadata correction proposals

* *Lexicons with a Language other than English* - remove from Intermediate Greek-English Lexicon, Abridged BDB

* *Lexicons with Subject containing O.T. or N.T.* - inconsistently applied across all type:lexicon e.g. Lexham Analytical Lexicon to the Septuagint doesn't have O.T. Suggest applying to all lexicons covering a *single* Testament.

* *The Life of Christ: A Study Guide to the Gospel Record* - TYPE should not be "Bible Commentary" as it is a "Study Guide". /Otherwise/ list the bible books it covers for consistency e.g. N.T.John, etc.

* *Perseus Resources* - some resources have /pubdate:/ not following the usual convention of giving a four-digit year but give other date formats, this defies sort or select operations

* *Perseus Resources* - some resources have empty /pubdate:/ field
