quotas

JD indicated that he could no longer upload files under one of his accounts. I figured it was a quota somewhere. I googled "upload drupal quota" and found this post on drupal.org. It turns out that upload quotas are set by role. How nice. I increased the upload quota for site admins from 300MB to 500MB total for now. Will look into cleaning up eventually. This is in /admin/settings/upload (4.6) in case we need to bump again. Currently, max size per upload is set to 1MB for site and media admin roles.
