Added bower.json

(re: #10)

Once merged, all you'll need to do is:

```
$ git tag v0.1.0
$ git push origin tag v0.1.0
$ bower register console.image git://github.com/adriancooney/console.image.git
```

If you don't already have bower installed, it's simply: `$ npm install -g bower`.

For future releases, all you need to do is bump the [semver](http://semver.org/) number in the `bower.json`, create and push a new tag with the same number, prefixed with the letter "v".
