Building platform binaries

We can build Network Web Socket Proxy cross-platform binaries from this repository as follows:

Install goxc:
```
  $> go get github.com/laher/goxc
```
Build your own Network Web Socket Proxy binaries using the provided .goxc.json configuration file as follows:
```
  $> cd `go list -f '{{.Dir}}' github.com/namedwebsockets/cmd/networkwebsockets`
  $> goxc -pv=latest
```

Built platform binaries will now be available in $GOPATH/bin/networkwebsockets-xc/.
