Amazon S3 images return 403 with use of Equalizer

[corywest]

While using Equalizer with a production rails application, Amazon S3 images always fail and return a status code of 403. This problem was also found with issue #9697 with the foundation-sites repo. However, it seems this issue is still occurring with the rails gem.

I have reverted my personal code changes without the use of Equalizer and pushed back to production, only to find that everything works again with no issue at all.
