We use S3 for a number of uploads. Boto, by default, includes a auth querystring on the returned URLs. Since these uploads are public, there is no need for this querystring. Additionally, the long length URLs cause problems when API consumers need to store the URLs. This commit resolves this problem by removing the auth querystring.

- Updated to latest versions of boto and django-storages-redux packages
- Added AWS_QUERYSTRING_AUTH setting to remove the querystring values
