Bug 11453: Update EN default UNIMARC bibliographic framework

This patch updates default EN UNIMARC bibliographic framework

I used the 2008 version of the UNIMARC bibliographic manual,
and added updates listed on official site.

There are new fields/subfields, those added are hidden by
default.

There are some description changes, and also a lot of
changes to repeatable and mandatory values.

To test:
a) Functional
1) Remove all bibliographic frameworks
2) Load new file unimarc_framework_DEFAULT.sql
3) Check that it load without errors

b) Correctness
1) Take a time and verify that all new
fields/subfileds are correct
