Added a 'permanent' argument the simple.redirect_to() generic view. It's True by default, to match existing behavior. If set to False, the redirect will be a 302 instead of a 301. This is technically backwards-incompatible if you were using the redirect_to generic view with a format-string key called 'permanent', which is highly, highly unlikely.
