Use rune natural attack range for unarmed mobs

Unarmed mobs now add their rune natural attack range in processAttack
and use it in getRange. Most melee runes have 0, so they are unchanged;
ranged plant mobs (Gasser, Spitter, Needler, ...) get 150, Shuggra 50.
Natural range is not subject to the unverified 80 clamp.
