To test:
1) Apply this patch set
2) perl installer/data/mysql/updatedatabase.pl
3) In koha administration => item types, edit "Books" itemtype
CHECK => there is now a select multiple whith libraries at the bottom
4) select centerville and save
5) set centerville as current libary
6) search for any biblio in the catalog
7) click on "edit items"
CHECK => book item type is present
8) set any other libary as current library
SUCCESS => book item type is not present
9) Sign off
