Subject: [PATCH] - Class loaders for both frameworks:

eZComponents through a loader object
Zend Framework with an autoload function

Example usage:

require("{$phpbb_root_path}includes/ezcomponents/loader.$phpEx");
require("{$phpbb_root_path}includes/Zend/loader.$phpEx");

$loader = new phpbb_ezcomponents_loader();
$loader->load_component('search');

$handler = new ezcSearchZendLuceneHandler( '/tmp/lucene' );
