Alert prompts for BetterAuthorizationService

In Apple's BetterAuthorizationSample application pressing the "LowNumberedPorts" button brings up a window to authorize yourself. It includes the following text to explain why you are authorizing yourself: "You must be authorized to open low-numbered TCP ports. Type your password to allow B
