Bug 10178 - Typos in plugins for 006 and 008 in MARC21

Well, not only typos. There is also a NEW update for
006/8 Music on April 2013. And 3 missing values in 006.

Revised descriptions and labels, source LOC page.
Strings spell checked.

To test:
1) Apply the patch
2) Test that MARC21 006 and 008 value builders works
properly.

Small string changes.

Contains string changes, so should go into 3.14.

Trivial string changes that didn't make it before string freeze. Patch applies cleanly on 3.12.x. It shouldn't go into older releases I guess.
