Max length for vines

I believe vines and everything similar - such as kelp - looks pretty, but its biggest downfall is the fact that if you stay there for too long every vine would go all the way to the ground and every kelp ends up at the top.

My idea is to introduce a limit that has a range (for example 10-15 blocks) that is random, not only for removing excessive vines but also would make things look much nicer overall, especially with the edition of new vine blocks in the snapshots.

So basically everything works a bit like bamboo growing :D
