Set up initial values for defaults:
Create dictionary with keys and values for WordOfTheDay, FontName,
FontSize, and FavoriteColor.  Mostly straightforward, but:

Store the fontName of the font as the default; the textfield displays
the font's displayName using a value transformer.

The color must be archived -- you can't store NSColors directly in NSUserDefaults.
