Upgraded to latest ZF2 release (RC7); uncommented VuFind features that were waiting for functionality introduced in this release.

Eliminated __call method in \VuFind\Search\Base\Results; explicit getParams() calls make code more comprehensible.

Made getParams() calls more explicit; fixed bug where scroller did not work for non-standard page sizes.

Eliminated __call() method in \VuFind\Search\Base\Options; replaced with explicit getOptions() calls to make the code more consistent and understandable.

Made constructor injection of catalog connection into ILS logic classes mandatory to break unnecessary dependencies.

Refactored authentication interface for compatibility with plugin manager (moved configuration setting from constructor to setConfig() method).  Added some partial unit tests for uncovered authentication methods.

Changed ILS driver loading sequence for more flexibility.  No hard work is done in the constructor; instead there is an init() method that gets called by the VuFind\ILS\Connection class.  Additionally, drivers no longer load their own configurations; instead, configs are pushed in by VuFind\ILS\Connection, making reuse easier in other contexts.  Finally, ILS drivers all inherit from the same base class, easing future functionality.

PICA configuration now includes copy of DAIA settings -- this avoids the need to load two separate configs when using PICA.ini

Fixed a Symphony namespacing bug.

Stub tests have been added for all existing drivers, though they do not cover much code yet.

Created ILS view helper to eliminate direct access to \VuFind\Connection\Manager from within templates.

Moved DisplayDateFormat functionality from separate view helper into DateTime view helper to consolidate code.

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.
