Title: Allow debug: option to be specified as (integer) port number.

I needed to be able to specify a custom debugging port while using grunt-express-server. This patch enables this functionality.

In addition to `debug: true` and `debug: false`, this patch will take an integer as a port number to start the node debugger on. All of these are valid examples:

```javascript
express: {
options: {
port: process.env.PORT || 9000
},
dev: {
options: {
script: 'server/app.js',
debug: 5959
}
},
```

```javascript
express: {
options: {
port: process.env.PORT || 9000
},
dev: {
options: {
script: 'server/app.js',
debug: false
}
},
```

```javascript
express: {
options: {
port: process.env.PORT || 9000
},
dev: {
options: {
script: 'server/app.js',
debug: true
}
},
```
