Add "again" to the hit message when an attack sequence has
consecutive attacks of same type and they hit. A {bite, claw, claw}
sequence won't give that for first claw attack regardless of whether
the bite hits but will give it for the second claw attack when both
of the claw attacks hit.
The message sequence
|The fire ant bites! The fire ant bites! You're on fire!
or |The fire ant bites! The fire ant bites! You avoid harm.
when the first bite was for physical damage and the second was
for fire damage seemed a little confusing.
This changes that to be
|The fire ant bites! The fire ant bites again! You're on fire!
or |The fire ant bites! The fire ant bites again! You avoid harm.
It still isn't crystal clear that both bites are from a single
attack and that the second bite is for different type of damage
but I think it's an improvement.
