Echo json and form data from body

[justinmchase]

This fixes #2

This change parses the body so it is available to echo back using the standard express package body-parser.

NOTE: I manually "prettified" the json output below so it was easier to read.

Before

Notice the lack of "body" in the output:

$ curl -X PUT -H "Content-Type: application/json" -d '{"hello":"world"}' http://localhost:3000
{
	"fresh": false,
	"headers": {
		"accept": "*/*",
		"content-length": "17",
		"content-type": "application/json",
		"host": "localhost:3000",
		"user-agent": "curl/7.54.0"
	},
	"hostname": "localhost",
	"ip": "::1",
	"ips": [],
	"method": "PUT",
	"path": "/",
	"protocol": "http",
	"query": {},
	"subdomains": [],
	"xhr": false
}

After

Notice the presence of "body":{"hello":"world"} in the output now:

json

$ curl -X PUT -H "Content-Type: application/json" -d '{"hello":"world"}' http://localhost:3000
{
	"body": {
		"hello": "world"
	},
	"fresh": false,
	"headers": {
		"accept": "*/*",
		"content-length": "17",
		"content-type": "application/json",
		"host": "localhost:3000",
		"user-agent": "curl/7.54.0"
	},
	"hostname": "localhost",
	"ip": "::1",
	"ips": [],
	"method": "PUT",
	"path": "/",
	"protocol": "http",
	"query": {},
	"subdomains": [],
	"xhr": false
}

form-data

$ curl -X PUT -d hello=world http://localhost:3000
{
	"body": {
		"hello": "world"
	},
	"fresh": false,
	"headers": {
		"accept": "*/*",
		"content-length": "11",
		"content-type": "application/x-www-form-urlencoded",
		"host": "localhost:3000",
		"user-agent": "curl/7.54.0"
	},
	"hostname": "localhost",
	"ip": "::1",
	"ips": [],
	"method": "PUT",
	"path": "/",
	"protocol": "http",
	"query": {},
	"subdomains": [],
	"xhr": false
}
