Use exec to switch to node process

At the end of run, `exec` should be used to switch to the node process.  That way node will take over the pid of `sh run.sh`, making it easier to monitor and daemonize the server. 

```
    exec [command [arg ...]]
             Unless command is omitted, the shell process is replaced with the
             specified program (which must be a real program, not a shell
             built-in command or function).  Any redirections on the exec com-
             mand are marked as permanent, so that they are not undone when
             the exec command finishes.
```
