Neutral and enemy races

Members of hostile races and members of neither-friendly-nor-hostile races
are now displayed in a different way.

As usual, enemies are shown as *an Orc* or *an Elf* (highlighted).

Members of "neutral" races (e.g. a Bear to an Elf, or a Troll to a Tarkhnarb
Orc) are displayed as "-a Bear-" or "-a Troll-" (not highlighted).
