Support to call filter constructor with arguments

In Assetic, the Yui\BaseCompressorFilter constructor takes two arguments.

Calling filter constructor with arguments wasn't supported.

Configuration example :
        'filters' => array(
			'text/css' => array(
				array(
					'filter' => 'Yui\CssCompressorFilter',
					'args' => array(
						'jarPath' => __DIR__ . '/../library/yuicompressor-2.4.8pre.jar',
						'javaPath' => 'java',
					),
				),
			),
        ),
