ZF-6160: Zend_Application should have a autoloaderOptions key


Zend_Application should be able to configure the autoloader.


Currently, it allows you to pass an array of autoloader namespaces (via the 'autoloaderNamespaces' key). If you need more customization than that, it is recommended to either pull the autoloader from Zend_Application prior to calling bootstrap(), or to configure the autoloader prior to initializing Zend_Application.
