This patch adds a biblio CSV import which can be used for library migration to openbiblio.
The CSV import file must be a tab separated file (use any parser-converter to convert your CSV file to the usable format). It can include barcode numbers to
ease migration but it does not yet handle duplicates cleanly (currently, it will add a complete entry, not just a copy).
The import page describes the column names understood by the import tool. Most are represented by the MARC identifier, other (openbiblio-special enries) carry
own column names.
Before import, a dry-run feature is available (like in the MARC import) to check for a lot of error conditions (missing mandatory data).
Translation-ready (en part of this patch).
