Subject: [PATCH] Bug 3326: Work around Zebra's handling of &amp; entities

When using XSLT mode, the OPAC results display will show "&amp;" instead of "&"
when Zebra is indexing in XML mode. This patch works around this by replacing
"&amp;" with "&" and then extends the previous fix to apply to all occurrences
of "& " instead of just the first.
