Added monster MR display (petato, mantis-id 113).

    Adds a line to the monster description screen that tells you how
    resistant it is to magic. Uses the same scale as player MR (eg on the
    % screen) except it skips "not resistant" levels of (non-)resistance.

    Uploaded a new version of the patch; now includes experimental MR
    display rescaling for both players and npcs. Try it out on the %
    screen, or examine a creature. Adverbs stolen from the stealth
    display, crazy resistant creatures are described as "almost entirely
    resistant".
