Bug 6971: XSLT Opac Detail displays 245 subfields out of order.

Bug 6971: XSLT Opac Detail displays 245 subfields out of order.

245 Subfields in the OPAC Detail Display (MARC21slim2OPACDetail.xsl) are being
reordered on display. Instead of displaying 245$a 245$h 245$b, the stylesheet
was displaying 245$a 245$b 245$h. This patch does not address ISBD punctuation.
