1.6.2

I started working on the Sickle (I know you had it on lower priority, but that's where I can give you a hand).

For now I've just added the Iron Sickle, I'm planning to add the other ones, but I wanted to hear if you want those also (wood, stone, diamond, gold, the gems ones, and even from other ores).

I'm creating this PR just to get some initial feedback, I don't expect you to merge it now, as I plan to update it throughout the next days to improve it (I kindly ask to not close abruptly before I finish it, I'll notify you when I'm done).

I was thinking in some ideas:
1) instead of making the sickle 3x3 on leaves and and 5x5 on crops
a) I was thinking on doing the opposite
b) or even making it 5x5 on everything
c) or even keeping the 3x3 on leaves and make it work on 5x5 on tall grass, flowers and alike

I'd love some feedback on your thoughts
