Bug 9610 - Spanish translation of MARC21 default bibliographic framework

This (large) patch adds spanish translation to default
MARC21 bibliographic frameworks.

Based on final EN default framework of Bug 5858,
strings from http://www.bne.es/es/Micrositios/Guias/Marc21/index.html

Automated substitution of strings, to change as
little as possible the original file and ensure
that no entry is removed.

Only to new installs.

To test
1) Delete default framework.
2) Load installer/data/mysql/es-ES/marcflavour/marc21/mandatory/marc21_framework_DEFAULT.sql
   into database. Must load without errors.
3) Edit a record y choose default framework, legends must be in spanish
   (save for obsoleted fields, left untranslated on pourpose)

SQL changes only.
Dropped my database and ran the Spanish web installer with
all sample files. No errors and frameworks in Koha look fine.
