Multiplayer infinity bone meal

Hi, I'm Ray.
I want to report a bug for 0.4.0 multiplayer.
The problem is the person who joined the game get a infinity bone meal.
That person can use bone meal for infinity, even that person has a 1 bone meal.
I really want this bug to be fix for the balance in multiplayer.
Also, if you have some times to fix a bug for multiplayer, please fix the cactus bug (joined person doesn't get any damage from cactus)

Thank you for reading my description of a bug. Sorry for my bad English...

Thank you Mojang! 😃
