How about differenciate errors

[pablovilas]

At the moment the event emitter fires a single 'error' type for message errors and queue conection errors. Would be great if those errors are separated in 'error' and 'message_error'. For example if you want to leave the message in the queue because you can't process it at the moment a message_error would be fired.
Also would be nice if a re-poll option is added when polling the queue fires an error.
I can do a pr for that If you are agree.
Thanks

Hi @pablovilas. This is a duplicate of #16 so I'm going to close, but would be happy to welcome a PR for two separate error events.

error should be an AWS client error
processing_error should be an error returned to done for ease of logging

As for re-polling, we already start a new poll on error. If this behaviour isn't working for you, please raise a separate issue for it with an example.

Sorry about duplication. I didn't see that there is no return keyword, so re-polling will work.
