New Tower: Seed Dump

We should not have to rely on the algae blooms for waste digesting algae! We can now build a Seed Dump which pours special seed in powder form which swiftly generates algae in the water used in other biochemical digestive reactions (killing poops).

Comes with upgrades to amount of seed poured. Note! A chem dump tower too close can largely negate this tower's usefulness.
