fixed leafdecay!!


ok why has no one noticed that the if param2 ~= 0 return for leafdecay never worked to save self placed leaves????

it doesnt work because its missing this bit of code was not in place to set param2!

i have tons of players on my servers and the ones a admin/moderate thet hate that the leaves cant be built with!!






sorry for the last pull request, github didnt do my changes correctly
