python-urlgrabber update to 3.9.0

[Seth Vidal <skvidal fedoraproject org>]

Hi,
 I've pushed python-urlgrabber 3.9.0 into rawhide. It is an api-compliant 
urlgrabber - but it is now backended to libcurl instead of urllib2. In 
tests so far everything appears to work as intended. However, please let 
me know if something seems odder than normal  with this change. We can 
revert back to 3.1.X pretty easily.

Thanks,
