Rename ValuesAsArrayOfStrings to StringValues; this method now raises a TypeMismatchException when some array element does not inherit from NSString instead of skipping; fix several occurrences of a bug in NSFontManager in which NSArray.VariantValue was being returned instead of a String array.
Remove commented-out code.
Clean up code here and there.
