Huge thank you to DavigJ for the entirety of this update!
interacting with dandelions (and using bloom meal successfully) now triggers appropriate arm swings
spawn egg interaction now places a sprout at the blockpos the dandelion is inhabiting; if already occupied or otherwise not placeable, a sprout is then sent out
dandelion seeds now go in more than one direction (breeding causes the multiple seeds to actually go in the locations intended)
seeds spawn particles along the way, increasing visual feedback
seeds that land on not-good terrain drop item entities of the sprout instead (though maybe that shouldn't happen..maybe the unsuccessful seed should die in a puff of smoke)
sprouts can be bonemealed to reduce the timer to grow
