Escape split the action "Poison City"
Stop relying on the "Spy" unit type flag to decide if performing the action "Poison City" consumes the actor unit. Split out a new action called "Poison City Escape" from the original action. The new action will have its actor try to escape. The original will always consume the actor unit.
This is the last use of the "Spy" utype flag to determine if an action consumes a unit.
