Add a new middleware that tells you who you are; IP, port and transport is echoed back. Also some various cleanup and documentation improvements while at it: * ResponseWriter: improve the documentation of these helper functions. * And add an NextHandler for use in tests. Make chaos_test.go and * whoam_test.go use it.
