Require six>=1.4.1
Releasing version 1.0.3
Use bytes as default file content type.

This is a workaround for the case when `InMemoryStorage._save()` gets
passed bytes as the `content` argument, but the file was already created
with `StringIO` as an underlying stream class. (`InMemoryFile.__init__`
determines stream class by looking at `content` type.)
