Prevent error if DBBACKUP_MEDIA_PATH not supplied
fix Broken Pipe issues by actually respecting the DBBACKUP_S3_DOMAIN property. Added SSL support option (default True). Updated readme
Allows fallback to MEDIA_ROOT if DBBACKUP_MEDIA_PATH isn't defined.

This function would previously crash if DBBACKUP_MEDIA_PATH
wasn't defined in settings, which does not seem to be the
intended behaviour.
