Revisions to auto-generated authorities patch

Revisions to auto-generated authorities patch

It turns out that the "blank" record created by MARC::Record->new()
has a leader, so now I explicitly create one in addbiblio.pl.  I
also realized I can't count. :-)

Modified per comments by Joe and Galen to keep SetMarcUnicodeFlag
and move it and the leader set to earlier in the process.
