non-humanoid lawful minions wearing armor

<Someone> reported that couatl and ki-rin could wear boots and gloves.
Two problems: 1. all minions were created with a sword and armor, even those
that couldn't use them.  2. couatl and ki-rin were missing some important
bits in their M1 flags.
Now neither couatl or ki-rin are created with armor, and they won't try
to wear any armor they cross in the dungeon.
