Extend NpTextBox to support hinting and use it.

Create a new class: HintTextBox. This class extends NpTextBox and can display a hint text when the text field would be blank. This class will keep track of whether the hint is currently being displayed or not and set the style to hintStyleName if the hint is currently displayed. This class will also modify the getText() method to never return the hintText unless a user enters this text manually. Use this new class everywhere where hinting was previously implemented manually.
