Hydroponics tray is now a machine that can be upgraded with bigger matter bins for more water and nutriment capacity.
Tray icons will now only update when necessary.
Added cream, plant bag and mining satchel to biogenerator.
Biogenerator's messages are now shown on top of the menu, instead of a separate screen.
Examining the tray now tells you the name of the plant.
Hydroponics trays start without nutriment, more E-Z-Nutriment added to vendor to compensate
Seed vending machine's contents are now sorted.
Less snowflake-y
