Hi Team,

I have added ignoreTube as well as getResponseLinesText method @ incubator/Library/Phalcon/Queue/Beanstalk/Extended.php as per beanstalk protocol defination (https://github.com/kr/beanstalkd/blob/master/doc/protocol.txt) to ignore any watched tube.

It is working fine at my laptop and server. Please review and provide this feature to rest of world.

Thanks in advance for providing such a greate framework.

Regards
