Added route to serve static files

Because in development mode i use nekoserver to test the server (with no nginx or apache) is very useful to have static files being served by the ufront app.

I used the folder structure : 
```
./public - images
            - javascripts
            - stylesheets
```

In the fashion of Express.js generator.

Let me know what you think, i also think that using sqlite would be a good idea, because then the hello world would be ready to use out of the box (no dependencies), also added the only server start command that works for me to the documentation (using windows).
