Expanding the error-handling and capabilities of the Record.pm API.

Expanding the error-handling and capabilities of the Record.pm API.

This module represents a major leap forward in Koha's support of standard
record formats (ISO-2709 (MARC), MARCXML, Dublin Core, MODS, etc). It
provides a standard API for record management as well as an error-handling
mechanism so that the API will return proper error strings to the calling
program. It's only partially implemented currently, but the API returns
proper error strings if a feature isn't implemented.

There is also a testing suite that you can use to check your system's
capabilities to handle record and encoding conversions. Commit coming
soon.

I'm gonna work in UNICODE support next ...
