Build static mobs from zone mobiles with their CZONE runes, equipment and booty

Mob.createStaticMob fills one member of a MOBILE zone mobile's group:
race rune as mobbase, name, mobile_level (kept over the mobbase level
when set), respawn, radius, root FSM, enemy types and π − y_rot facing.
Static mobs send the CZONE rune list ordered by kind, wear
mobile_equipment and roll mobile_booties as ITEM booty. Other mobs keep
the server-picked runes and equipment sets.
