Add animation support

Allow the AST to pick up `animation`s and annotate them appropriately, e.g.

```javascript
module.animation('animation-fade-enter', function($jq, _) {...});
```
becomes
```javascript
module.animation('animation-fade-enter', ['$jq', '_', function($jq, _) {}]);
```

Tested this locally with `ngMin` - sorry, not sure if there are other tests to perform.
