- Resolves VUFIND-1197

- Wired up case sensitivity setting through factories
- Simplified tag searching vs. exact lookups to reduce redundancy
- Made Tags::getByText more flexible for more accurate/efficient deletion
- Adjusted upgrade script so that existing "duplicate tag" fix accounts for case-insensitivity

- Includes upgrade script support.

- 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.
