[WIP][Do not merge!] New plants

*Adds a new plant: The singulo potato. You can crush it in your hand to create a singularityhammer vortex effect that will pull nearby items and people to you! Range and stuntime is dependent on potency. Stun is capped at 4 ticks. Note that this does no damage at all.

TODO: Sprites!

*Adds a new plant: The spiderplant. The spiderplant mutates from eggplants and yields spiderpods. Spiderpods have 3 uses:
1. You can grind them to get poisons.
2. You can cut them into pieces to get spidermeat for cooking. The amount of meat depends on the potency of the pod. The meat also includes all the reagents that were in the pod when cut!
3. You can pry them open to possibly release a spiderling. The chance of it working is pretty low and even at potency 100 it is only 60% so you better work hard if you want to fill the station with spiders!

Spiderling spawning and attempted spawning with the pods is logged for admins too.

TODO: Sprites!

*Walking mushrooms can now go on a rampage! Feed them killer tomatoes(placeholder for now) to make them fight every creature, not just other mushrooms! Do note that they will still fight each other to death so using more than 1 mushroom for a murder spree is greatly discouraged. Rampaging mushrooms won't attempt to devour other mushrooms and can't level up anymore.

Todo: Expand walking mushrooms a bit, balance their values a bit more. Maybe a frightening custom sprite depending on their level?

*Makes blood tomatoes spawn gibs on squashing.

TODO: Make it dependent on potency.

I would greatly appreciate spriting help with this. All sprites are currently placeholders...
