Subject: [PATCH] Changes the corrosion message to give the previous state of
 the corroded item too.

For example, "The acid corrodes your +0 robe" is now "The acid corrodes your +1 robe into a +0 robe"
Previously the corrosion message was misleading because it implied the +0 was old state, rather than the new state.
To remove this ambiguity, both the old and current state are displayed in the notification.

Subject: [PATCH] Corrosion msg now uses correct enchantment level

The corrosion message displays current enchantment level rather than old
enchantment level.
e.g When a jelly corrodes your +1 robe to a +0 robe, you see
"The acid corrodes your +1 robe" instead of "The acid corrodes your +0"
