attachment_fu_s3_cache
======================

Extend Attachement Fu to cache S3 files locally on the server. Uploaded files are stored to your server. You then need a 
cron job to prompt this plugin to copy the files off to S3. Another cron job checks disk usage against a quote you set 
to clear files off the server that haven't been touched in a while.
