Download all in one scripts function added.

Module waiting for scripts loaded to init.

Implemented a demo of nodejs server with allInOne function.
Es muy buena la idea, eso está solucionado así

```js

<script src="preload.js"></script> //Esto va en el index

app.use(/^.+preload.+js$/, function(req, res, next){
	//If you are development in this project, you want this here
	var fileDirAndName = developmentMode ? 'src/preload.js' : 'dist/preload.min.js';
	res.sendFile(path.join(__dirname, '../../', fileDirAndName));
});
```
