/** Attempts to use the bonemeal on the plant at the specified (absolute) position.
The effect of fertilization depends on the plant: https://minecraft.gamepedia.com/Bone_Meal#Fertilizer
- grow a few stages
- grow 1 stage with a chance
- drop pickups without destroying the plant
- grow more plants in the vicinity
If fertilized succesfully, spawn appropriate particle effects, too.
Returns true if the plant was fertilized successfully, false if not / not a plant.
Note that successful fertilization doesn't mean successful growth - for blocks that have only a chance to grow,
fertilization success is reported even in the case when the chance fails (bonemeal still needs to be consumed). */
