All Zebra config files are now installed by default. The
ones specific to a MARC format or language are selected
by appropriate values in profilePath in zebra-biblios.cfg
and zebra-authorities.cfg. Changing the MARC format
or indexing language can now be done by editing
profilePath.
Inspired by work by Chris Cormack, move several base Zebra
configuration files to two new directories under etc/zebradb:
lang_defs - language-specific settings (e.g., French and English)
marc_defs - MARC format-specific settings (e.g., MARC21 & UNIMARC)
Installer will query user for language and MARC format and
copy the inital Zebra configs accordingly.
