Route uploads through async-upload.php instead of admin-ajax.php
|Reported by:||koopersmith||Owned by:||ryan|
wp.Uploader sends its uploaders to admin-ajax through the wp_ajax_upload_attachment() method instead of to async-upload. While the resulting code is cleaner, some installs may have async-upload whitelisted and/or provisioned differently than admin-ajax, resulting in errors (including but not limited to differing file size limitations).
After discussing in IRC, we're going to route everything through async-upload for 3.5.
