rework Log::players/npcs

Since we know that we're only returning Agents which are Players, we can
save downstream users some time and also provide access to the &Player.
Ideally, we'd want something like PlayerAgent, or Agent<Player>, but
that not only incurrs code duplication (in the first case), it'd also
mean cloning the player data (second case), as we couldn't just return a
reference into the pool with all agents.

For now, this is still the better option, until other ways have been
explored. Maybe cloning here wouldn't be too bad, but we'd also run into
the issue that we cannot use record unpacking for records that have
different generic parameters, so going from Agent<AgentKind> to
Agent<Player> would mean manually copying over all record fields.

We now no longer need the matches! macro, as we can simply use
AgentKind::as_{player,character}.
