Swarming Colony
When the player has instructed a colony to Swarm a swarming colony is created near the colony after time X (4 hours?).
Any user in the same faction may Pick Up it if they have space in Inventory.
A swarming colony is used to start a new Colony in an empty Nest.
If a swarming colony is not picked up after X time period (one week?) it will disappear.
