Clean up Pikel band code, name them "slaves", then "freed slaves".

As per kilobyte's suggestion on c-r-d, Pikel's humans are named "slave"
until they are released from bondage on Pikel's death, in which case
they're called "freed slave".

Also clean up the Pikel band neutralisation code: instead of assuming
that all human monsters that are band members are Pikel's band, store a
value in monsters.props that signifies them as such.
