retools.queue butchers queue names

[msabramo]

I use a queue named "long" and I noticed that the process title was always "retools: Waiting for ng" for some strange reason.

Tonight, I finally looked into it and found out why.

It's because lstrip doesn't do what the author of the code who used it thinks it does.

>>> queue_name = 'long'
>>> queue_name.lstrip('retools:queue:')
'ng'

This inappropriate usage is in 2 places:

• https://github.com/bbangert/retools/blob/master/retools/queue.py#L364
• https://github.com/bbangert/retools/blob/master/retools/queue.py#L431

I'll send a PR to fix this...
