Bug 9826 - Missing fields in MARC21 authority framework

This patch updates MARC21 authority framework adding
missing tags/subtags up to Update No. 15 (September 2012)

Missing tags and corresponding subtags only added to
default authority framework.

For present authtypes only missing subtags are added.

Also updates a few legends to match those from LOC.

No deletions except for a few not relevant tags in
present authtypes without subfields.

Only to new installs.

To test:
1) Delete present authority frameworks
2) Load new frameworks. On default there are
many new tags/subtags. On present authtypes
only a few new/renamed subtags.
