Updated bower.json

I changed the CSS reference from 
```
dist/css/pizza.min.css
```
to 
```
dist/css/pizza.css
```
...since there isn't a minified CSS file included with the package. 

It's minor, but it becomes an issue when working with tools like [wiredep](https://github.com/taptapship/wiredep), which automatically injects your bower components into your source code by reading the references listed in a package's `bower.json`.

I also bumped the version to `0.2.3`
