Smoke changes

- Changes smoke so that it immediately affects all mobs in its area of
effect, smoke clouds are purely visual.
- Any mobs in the area of effect of a smoke reaction will be affected by
the smoke's touch reaction, and have all reagents in the smoke container
transferred into them.
- Smoke clouds are no longer opaque.
- Mixing 10u potassium, 10u sugar, and 10u phosphorus or higher will
cause an area of effect with a radius of 3 from the point of reaction.
Any less will have a radius of 2.
- Same with heating 10u smoke powder.
- Smoke powder reaction now only yields 1 powder instead of 3.
- Vent clog event has a radius 3 area of effect.

Fixes and uncommenting

- Uncomments honey turf reaction.
- Uncomments synthflesh turf reaction.
- Adds list for reagents to not copy via smoke (or more specifically,
delete when a smoke reaction happens without copying). This includes
sugar, phosphorus, potassium, and the smoke "reagent" produced in a
smoke reaction.
