Title: Fixed precedence bug in Context.prototype.checkEmpty.

There is a small operator precedence bug in the ```checkEmpty``` function. The predicate compiles to

```javascript
$.isEmptyObject(this.waypoints.horizontal && $.isEmptyObject(this.waypoints.vertical))
```

which can result in the loss of waypoints. This fixes it.
