Made the SMBShareConnection slightly more robust. Introduced v2 List API to S3 backend, currently it retains v1 as the default. Changed S3 backends to not recurse, potentially making smaller listings. This option can be disabled if it breaks things. Added support for relative paths in the SSH backend.
