- Adds new database table for correlating external sessions to internal ones
- Includes command-line tool for maintenance

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

Configure ILS encryption hash algorithm.
* Includes hash conversion util script.

- Adjusted wiki links to point to latest URLs.
- Removed VuFind2 category name (use generic VuFind instead).

- Builds upon earlier work by mbeh-ub and others in PR #246.

- Progress on VUFIND-1035.

Renamed VuFind\CLI module to VuFindConsole for cleaner layout.  Changed return value for expire_searches.php so that "no searches were found to delete" is a success rather than a failure.

Temporary workaround for CLI compatibility problems in RC1; we should eventually integrate this properly with the native ZF2 console support.
