lp1040381: match up Subj and SubjUse fixed labels

Update the labels used in the fixed field editor for
authority records to match OCLC's labels specified at

http://www.oclc.org/support/documentation/worldcat/authorities/authformat/default.htm

This is consistent with commit's e675b854 change to the
OCLC labels, and also fixes a problem where changing the
008/11 and 008/15 was not reflected in the fixed field boxes.
