Fixingup error returns for directives (#26)
The processing of pkg/directives/patch.go will return an error type but
handeling of it was attempting to use JSON encoding to print to screen.
There is no reason to use that since the `error` type only has a string
in it but doesn't get marshalled properly to json due to the private
variables.
This is also the only time json marshaling is used so instead covert the
error handling to just `fmt.Printf`.
