Added bower.json file and registered jquery-lang-js with bower.

Ok, I have registered jquery-lang-js with bower. The file bower.json contains all the data for bower.

When creating a new tag, be sure to update the version in bower.json to match. That's all.

You can install jquery-lang-js with:

```
bower install jquery-lang-js
```

or you can view info with:

```
bower info jquery-lang-js
```

More info can be found here if you need it: http://bower.io/#defining-a-package
