added default values

Hey!

I've added two public properties:

```
Goodnight.from = 18; // 6PM
Goodnight.to = 6;    // 6AM
```

I also bumped the version (to 0.1.1) and minified the new changes.

Default values could probably be added to the .css() function. Like this: `.css(path, options)`, but I'll leave that up to you to decide.
