Bug 13510 - Cross site scripting bug in opac-downloadshelf and opac-shelves

A specially crafted url causes XSS in Koha

To test:

cgi-bin/koha/opac-shelves.pl?viewshelf=2%22%3E%3Cscript%3Eprompt(987898)%3C/script%3E

cgi-bin/koha/opac-downloadshelf.pl?shelfid=2%22%3Cscript%3Eprompt(1)%3C/script%3E&showprivateshelves

These should cause a popup without the patch. With the patch, no popup.

You may need to create these lists, the xss will not be triggered if the list doesn't exist or you don't
have permission to view them.
