Subject: [PATCH] Bug 11307: Fix potential XSS attack in public catalog RSS
 feed

To test:
1/ Craft a url like
/cgi-bin/koha/opac-search.pl?q=a&count=50"'<h1>test</h1>&sort_by=acqdate_dsc&format=rss2
2/ look at the source, notice
<opensearch:itemsPerPage>50"'<h1>test</h1></opensearch:itemsPerPage>
3/ apply the patch, and reload url
4/ source now contains
 <opensearch:itemsPerPage>50&quot;'&lt;h1&gt;test&lt;/h1&gt;</opensearch:itemsPerPage>
