In BasePayload, ensure any Django ugettext_lazy (or similar) are converted to real strings before handing off to ESP code. This resolves problems where calling code expects it can use lazy strings "anywhere", but non-Django code (requests, ESP packages) don't always handle them correctly. * Add utils helpers for lazy objects (is_lazy, force_non_lazy*) * Add lazy object handling to utils.Attachment * Add lazy object handling converters to BasePayload attr processing where appropriate. (This ends up varying by the expected attribute type.) Fixes #34.
