New space race trait: Spore colonization

[tuomount]

Spore colonization would that space race with this could not build colony ships, but instead spores. These would be cheap ships with slow engine. Only two slots, engine and spore module. No need for adding colony on board. These would be seen as privateer ships. These would colonize uncolonized planet as normally. If planet is already colonized, one spore would destroy one population from planet. So planets could be conquered by sending swarm of spore ships. Of course these could be destroyed in normal space combat or even shot down with planetary turrets. Strangely zero-gravity beings would be protected from spores, since they are not living on planet.
