Better messages for monsters coming into view.

When more than one monster come into view at once, there's a single message
listing the various monster types. If there is more than 4 types, we list
genera (which is the correct plural of genus :). If there's more than 4
genera, we fall back to "x monsters come into view."

Examples:
4 orcs, an orc wizard, a troll and Psyche come into view.
3 dragons and 6 draconians come into view.

This is commit is also a preparation for the futur Ash ability of
identifying monster equipment.
