Adding newline to end of response body

[montanaflynn]

Using the Kong admin API I noticed it doesn't include a newline after the response body. When using with a CLI tool like cURL this makes for a bad developer experience.

without newline:

$ curl 127.0.0.1:8000
{"message":"API not found"}$ curl 127.0.0.1:8001
{"hostname":"","tagline":"Welcome to Kong","version":"0.1.1beta-2","plugins":{"enabled_in_cluster":{},"available_on_server":["keyauth","basicauth","ratelimiting","tcplog","udplog","filelog"]}}$

with newline:

$ curl 127.0.0.1:8000
{"message":"API not found"}
$ curl 127.0.0.1:8001
{"hostname":"","tagline":"Welcome to Kong","version":"0.1.1beta-2","plugins":{"enabled_in_cluster":{},"available_on_server":["keyauth","basicauth","ratelimiting","tcplog","udplog","filelog"]}}
