Missing parameter for intermediary / root / Chain certificate

The nodejs module is missing the SSL parameter to set the intermediary CA certificate. This intermediary is required for many certs, including GoDaddy's, and should be mapped to the 'ca' option of express.createServer().

The attached patch adds a new parameter to nodejs.config.js.example called sslCAPath, which defaults to ''.

Then inside server.js, an extra if/else block checks for whether it's defined and if so passes it in with the 'ca' parameter.

  // server.js line ~1017
var server;
if (settings.scheme == 'https') {
	if (settings.sslCAPath == '') {
	  server = express.createServer({
	    key: fs.readFileSync(settings.sslKeyPath),
	    cert: fs.readFileSync(settings.sslCertPath)
	  });
	}
	else {
	  server = express.createServer({
            key: fs.readFileSync(settings.sslKeyPath),
	    ca: fs.readFileSync(settings.sslCAPath),
	    cert: fs.readFileSync(settings.sslCertPath)
	  });
	}
}

Using this patch I can use my GoDaddy SSL certificate with nodejs.module.
