Change the wording slightly if the hero simultaneously (in theory)
reverts to normal form and splahes acid on his/her attacker. Giving
the passive counterattack message first would be better, but several
types of counterattacks need to know in advance whether the hero has
reverted, producing a chicken-vs-egg seqeuncing situation.
I also took out 'register' directives from a bunch of declarations
since they'd been pretty much applied blindly rather than in
circumstances where someone evaluated the situation and decided that
they might matter.
