Subject: [PATCH] Fix arbitrator language selection prompt text

After selecting a language from the combobox, it would no longer
display the prompt text and instead would be blank.

As per the documentation
https://docs.oracle.com/javase/10/docs/api/javafx/scene/control/ComboBoxBase.html#promptTextProperty:
> Prompt text is not displayed in all circumstances, it is dependent
> upon the subclasses of ComboBoxBase to clarify when promptText will be
> shown.

Therefore, use a custom buttonCell on the combo box to display the
prompt text.
