Bug 3652: close XSS vulnerabilities on biblionumber and authid

Browse source 
Previously we did not sanitize biblionumber and authids passed in by
the user.

To test:
1) Go to /cgi-bin/koha/opac-detail.pl?biblionumber=2hi (substituting a
   valid biblionumber for the 2).
2) Notice the presence of "2hi" on this page, and also on the ISBD and
   MARC views.
3) Go to /cgi-bin/koha/opac-authoritiesdetail.pl?authid=2bye
   (substituting a valid authid for the 2).
4) Notice the presence of "2bye" on this page.
3) Apply patch.
4) Notice that "2hi" and "2bye" strings are gone.
