Make _increase_durations set values proportional to delay

_increase_durations is used by ozocubus armour, stonemail, rmissile
dmissile, regen, swiftness, fly, insluation, rpoison, control teleport,
ring of flames, confusing touch, and sure blade.

I modified it to add numbers proportional to normal movement delay
instead of using the number of turns an enchantment should last
directly.
