Bug 9820: display titles in MARC21 name headings better in XSLT mode

Prior to this patch, if a 100/700 had a $c, it would be
displayed with no space between the contents of $a and $c in XSLT mode.

For example,

100 1#$aSeuss,$cDr.

would be displayed as

SeussDr

The problem was caused by the original version of the stylesheets
drawing a bit too much from the MARC21 to MODS transformation.

To test:

[1] In a MARC21 database, turn on XSLT display mode for
    staff and OPAC.
[2] Create or identify a bib that has a 100 or 700 field
    with both a $a and a $c.
[3] Before applying the patch, verify that the name is
    displayed in bib details and search results with the
    name and title squashed together.  For example, "SeussDr"
[3] After applying the patch, verify that the name displays
    in bib details and search results with a space and
    intervening punctuation between the name and the title.  For
    example, "Seuss, Dr."
