Patch to Django Extensions

I am really loving the django-extensions project, especially the sync_media_s3 command to move my media to be hosted on Amazon S3.

I find it increasingly useful when combined with django- compress. However, I ran into a snag today where I wanted to only sync to s3 my compiled scripts from django- compress, instead of my entire MEDIA_ROOT.

Therefore, I added the a patch to add a \--dir optional parameter to the command.
