Set up session handlers to use a plugin manager; adjusted handler classes to use a setConfig() method instead of constructor injection to allow plugin manager compatibility.

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.

Replaced singleton nature of VuFind\Cart with use of the ZF2 service manager; fixed bug with removing items from cart via AJAX.

Moved \VuFind\Summon class to a view helper; it was only accessed in views, and using a helper makes template syntax cleaner.

Upgraded to ZF2RC5; this allows us to enable translation caching and simplify use of the forward() plugin.

Added unit test for ILS authentication; made ILS authentication module more testable (with optional dependency injection) and less error-prone (isset checks to avoid notices).

Progress implementing caching; language caching temporarily disabled due to bug in Zend translator component.
