Title: Registry::extract() method and a test for it

New method to extract a portion if data as new Registry instance.
Example of use:

$config = new Registry();
$config->loadFile('really-huge-json-config-for-all-systems');
//Routines
$rendererConfig = $config->extract('renderer');
$rendererConfig->set('templates.dir', '/path/to/templates');
$renrerer = new Renderer($rendererConfig);
