Bay hydroponics Rewrite port

Makes hydroponics possibly more !!FUN!!

Things can mutate into anything, possibilities include a self propogating ambrosia vulgaris weed that creates cyanide upon harvesting.


This is a near-total Hydroponics rewrite. It isn't finished but it covers the functionality currently existing on the server and more.
COMPLETED FEATURES

HYDROPONICS

    Closed hydro trays are now possible, taking atmospherics from a portables connector beneath them.
    Lysis-isolation centrifuge and ballistic delivery system are in, allowing for gene modifications.
    The plant analyzer has been rewritten from the ground up to be more useful and immersive.

SEEDS AND PLANTS

    Seed/plant/product data is stored in a set of global seed datums.
    These datums can diverge to form new species and be manipulated via genetic engineering.
    These datums handle harvesting and mutating independantly of hydroponics trays.
    Mutant species varieties are now handled in a modular way.
    Plants now have ideal heat, light and pressure values, as well as tolerances for differences.
    Plants can produce multiple different kinds of product.
    Reagent information is held in the datums rather than the product item.
    Arbitrary living products are now possible (current legit case is dionaea).
    Bioluminescent plants and vines are both possible.

SPACE VINES

    Space vines are now plantsegments pathwise in view of future intentions to make them more general.
    Spawned event kudzu should be identical to the current master implementation as it has no seed datum and ignores all the new code.
    Space vines now make use of seed data if spawned with a reference and can be harvested from.
    Vines now cause physical damage if they are carnivorous, and inject reagents if their seed data includes them.
    Vines will die if they find themselves in area outside of their tolerance.

Shouldn't icon files be in the icon folder?
