Update JavaFX 8 Tutorial for JDK 8u40

* Remove controlsfx dialogs and use the now included JavaFX dialogs instead.
* Reference the updated example downloads (v1.1).
* Add an info box for `setCellValueFactory` when used with `IntegerProperty` and `DoubleProperty` in part 2.
* Correct some minor typos.

-* With JavaFX it's common to use [`Properties`](http://docs.oracle.com/javase/8/javafx/api/javafx/beans/property/Property.html) for all fields of a model class. A `Property` allow us, for example, to automatically be notified when the `lastName` or any other variable is changed. This helps us keep the view in sync with the data.

 2. We'll add some instance variables that give us access to the table and the labels inside the view. The fields and some methods have a special `@FXML` annotation. This is necessary for the fxml file to have access to private fields and private methods. After we have everything set up in the fxml file, the application will automatically fill the variables when the fxml file is loaded. So let's add the following code:

 * The `setCellValueFactory(...)` that we set on the table colums are used to determine which field inside the `Person` objects should be used for the particular column. The arrow `->` indicates that we're using a Java 8 feature called *Lambdas*.
