Bug 27120: Send biblio to Koha plugins hook 'intranet_catalog_biblio_tab'

Koha plugins hook 'intranet_catalog_biblio_tab' should have the datas of the current biblio record.
Koha::Biblio is aleady in template, send it with hooks call.

This will be very usefull to be able to fetch external datas
(wikipedia, youtube, ...) depending on current biblio record.

Test plan :
1) Enable Koha plugins
2) Install plugin attached to this bug
3) Go to staff interface on a biblio record details page
4) Check you see tab 1 containing 'Tab for record {title}'
5) Check you see tab 2 containing 'Tab for record {isbn}'
