Moon Dog Howl can hit friendlies with its fear/damage effect

[jmerry]

The spell description says "Damages and instills fear in enemies who are evil". But since the spell uses an indiscriminate projectile, it can also hit non-enemy creatures if they're evil. Descriptions are pretty consistent about this in general - if it says "enemies", that's what it means.

I know there's already something in the fixpack on this spell ... but that seems to just be about simplifying the implementation with a subspell rather than a ton of EFFs. Nothing in what I read about hitting friendly evil creatures.

Recommended change: swap the projectile from INAREA (#94) to INAREANP (#159).
