Haskell Quiz/Posix Pangrams

RubyQuiz #97: Create pangrams (sentences containing every letter of the alphabet at least once) from the list of [utilities]. From the quiz page: "Pangrams should (1) use the fewest utilities and (2) have the minimum number of repeated letters. In either case, break ties on the other criterion; that is, your first solution should also have as few repeated letters as possible, and your second one should use as few utilities as possible." List of the utilities.
