Fix regression autotarget tunnel & blink staff bug

[zenzombie]

Fix a bug where some known good staffs of unknown kind (like blinking and tunneling) would not autotarget enemies, leaking information about the staff kind.

Q: Does this make more sense to fix in the next if statement? Instead of using target allies/enemies bolt flag, use magic polarity? I feel like that is the source of the leak - we shouldn't know bolt target from polarity, right?

Sure I can make that change probably this weekend.

@tmewett Ok I changed the flow. I think it's a lot cleaner now.
