Bug 28299: Take OpacHiddenItems into account on opac-shelves

hidden_items was not passed to XSLTParse4Display

2 things:
* Should we hide the biblio record if OpacHiddenItemsHidesRecord is set?
* allow_onshelf_holds is not working like in other scripts, what's the
expected behaviour? If hidden should we completely ignore the item?

Test plan:
1. Without the patch
2. fill OpacHiddenItems with «damaged: [1]»
3. find a record with several item
4. mark one of them as damaged
5. OPAC: go to the record, you shouldn't see the damaged item
6. add the record to a list
7. see the list
8. in Availability you see the damaged item mentioned, this is the issue
9. apply the patches and restart the services
10. the list should not mention the damaged item :D
