Custom 404

[mhemmings]

The default 404 message from rest.MakeRouter is not customisable.

Yes, writing a custom error handler in general is trivial, however I can't seem to find a way to override this default behaviour for requests that don't match a route.

Same thing for method not allowed.
There should be a way to define a custom error response format for all internal errors and any response from rest.Error
