Update to django-1.5 by removing obsolete patterns from urls.py
 and removing an obsolete property from URLField() in the model.
Add command to remove posts based on time of creation.
Implement --delta # to change the number of days to retain from
 the default value of 14 days.
Implement --list to show the slugified names of available feeds.
Implement --all to specify all available feeds.
Implement --full to completely purge posts for the specified feeds.
Example: manage.py feedjack_clean --delta 7 feed-name
Merge remote-tracking branch 'upstream/master'

	feedjack/views.py
Merge back in the deprecated links from upstream.
