Removed the EnumerateInstalledFonts() method (this now resides in StaticHelpers), and the call to it. Also fixed a bug wherein GreenLowerLevel was being assigned to twice, first with 0 (correctly), and secondly with 255 (erroneously - this assignment should have been made to GreenUpperLevel).
Changed the public IList<WordModel> Words property from a simple { get; private set; } accessor to a private/public combination of two List<WordModels>, so as to be able to call NotifyPropertyChanged when the property is reassigned.
Removed Brush property, which returned the Color property in a SolidColorBrush. Constructing SolidColorBrushes occurs on the UI thread, torpedoing any sort of test we might want to run on a WordModel or any object which references that property. Instead, the ColorToSolidColorBrushConverter will be used in XAML to convert the Color property in an identical fashion.
