[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: Add the seeds, add the actual plant, make new sprites. The object itself works already though!

*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: Needs sprites. Also have the cutting give spidereggs and legs randomly.

*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...
