- Includes updated tests.

If an empty PIN is passed to VoyagerRestful's changePassword function, check manually that the patron didn't have a PIN previously since Voyager fails to verify that. (#783)

Fixed VoyagerRestful request group response handling to work for recalls too (Voyager returns XML element 'hold' or 'recall'). (#781)

nlm_ojs.xsl has pre-vufind3 solr location in comment; update to the new one

- eliminates the need to install the troublesome PDO_OCI module.

- Unified the translation of request group and pickup location to use the same prefix in hold dialog and list of holds.

- The cluster library works correctly under SSL now by default.

- srand() served no real purpose here (randomization is automatic anyway; no compelling reason to specifically use a time-based seed for Demo purposes)
- perfect situation for use of array_map()

- Just some minor changes to avoid parameter expansion; I know that they are very unlikelly considering the script will run on specific conditions, but I think it's better to explicitly avoid this situation.

- All files reported by licensecheck[https://metacpan.org/pod/App::Licensecheck] were fixed.
