Openapoc: [Battlescape] Agents should not attack Chrysalis without a direct order

[FilmBoy84]

Chrysalis are harmless aliens and agents should NOT attack them automatically
They should only be attacked if the agent is ordered directly to do so by the player

Was this changed due to #594 ? I agree that ammo shouldn't be wasted, but OG had agents shoot at them regardless. They should be ignored but allowed to be shot at when commanded.
