play/mpuz.el improved

[Daniel Pfeiffer]

Hi,

Here now is the promised rewrite.  Due to the awkward internal
representation I've had to touch many places, and while I was at it, I
introduced some simplifications and modern improvements like bool vectors
and floats.

The result is smaller than a diff -u so I just send it all.

*** Enhanced game mpuz now allows the 2nd factor not to have two identical
digits.  By default all trivial operations involving whole lines are
performed automatically.  It uses faces for better visual feedback.

        * mpuz.el (mpuz-solve-when-trivial) 
        (mpuz-allow-double-multiplicator, mpuz-unsolved-face) 
        (mpuz-solved-face, mpuz-trivial-face, mpuz-text-face): new options for
        new features and nicer look

best regards
Daniel
