Replace corrosion with a temporary effect.

If your equipment would have been corroded under the old system, you now
get a temporary (but stacking) -5 AC and -3 weapon damage.  Corrosion
against armour-wearing monsters instead halves their AC.

Committer's notes:

    Fixed whitespace and fit to Trunk

    Added Corrosion entry to hiscores.cc

    The original patch showed the slaying malus on the weapon, which may
    be preferable to a status light.

    gammafunk noted that ouch.cc iterates over equipment when deciding
    when to corrode, this might make less sense under the new system.
