feat: flora 2.5 add bloodstream to trees, various tree and stump fixes

[Psymbiote]

Gives trees a bloodstream with a new reagent, resin, for blood. This PR paves the way for the introduction of cacti in flora 3, that will have a mix of sugar and water for their bloodstream.

Why / Balance

Giving trees a bloodstream opens up a lot of new possibilities, as certain species or even rare specimens can have different chemicals that can be sampled by botanists or scientists for round objectives or story purposes. Giving them the existing sap reagent wasn't deemed a good idea, as sap can be consumed to satiate hunger or thirst, that's why we made resin. There are some trees (notably the reeds of paradise) that do have easily consumable sap. The lamptrap plant also now comes with honey.

Technical details

• Parented BaseTree to MobBloodstream and gave them resin for blood.
