Bug 10431 - Spanish Zebra character sorting file

Bug 10431 - Spanish Zebra character sorting file

This patch provides a definition file for Spanish (es) character
sorting in Zebra. It is based on the ideas from Hugo Agud <hagud@orex.es>
and Pablo Bianchi <pablo.bianchi@gmail.com>.

Makefile.PL is fixed to notice the existence of the 'es' language. The
docs for koha-create are touched too.

To test:
Tarball
=======
- Go through the install process, choosing 'es' for the Zebra's language step
- Koha should work as usual.
- Running this should show the lang definition is properly set.
$ grep -R "lang_defs/es" /etc/koha/*
(stuff like zebradb/zebra-biblios-dom.cfg:profilePath:...etc/koha/zebra/lang_defs/es... should show)
- This file should be present:
 /etc/koha/zebradb/lang_defs/es/sort-string-utf.chr

Packages
========
- Build your own package, it shouldn't break the packaging
- Try the new package, using koha-create to set an instance using --lang 'es'
