Subject: [PATCH] Bug 14418 : More XSS vulnerabilities in opac-shelves.pl

To test:
1/ Hit a url like
/cgi-bin/koha/opac-shelves.pl?viewshelf=7&op=modif&display="><script>alert('oh
noes')</script>  Where the id is a valid shelf id
2/ Notice the js is executed
3/ Apply patch
4/ Reload page
5/ Notice input is now escaped on display

Tested in Debian, couldn't reproduce the alert in Iceweasel, but in
Chromium. Patch fixes it.
