Bug 13611 - Serial enumeration not visible in the opac-user.pl when browsing own holds.

Having placed holds on Serial Items with an enumchron, and browsing the
opac-user.pl's "Holds"-tab, the user cannot see which numbers of
magazines/serials he has on hold.

This patch appends the koha.items.enumchron after the title component in the
opac-user.pl's Holds-view.
