Adjust subjugator capacity for even number of slave runs

[matthewhively]

consider nerfing regular slave disks to 25mil (or 33mil?) pop per run (cut the attack duration in half though)
that way a subjugator with 4 disks will fill up in 5x4 runs (or nerf capacity of subjugator to 400mil so it fills up in 2 runs? at 50 mil each?)

How would this effect scavengers?
