Fixed Catwalks Desyncing/Ghost Blocking

[nightmarishblue]

Fixed the desyncs that occured due to the CatWalkBlock's getStateForPlacement() override, moving the logic into CatwalkBlockItem's place() method.
Catwalks placed on the upper half of a block now place in the right 1-block offset instead of producing desyncs (I'll test this more rigorously on a dedicated server). If the block above the player's cursor is occupied, it will place as normal. I don't know if NBT data is the cleanest way of doing this but I couldn't think of any other way to move the data between the item's place() and the block's getStateForPlacement().

Oh, right. This resolves #77 and possibly #84, as well as the closed #54.

Hi there, is there plan to implement this, or something similar?
I got the desync bug on my dedicated server, and more than that, just mouse-hover an iron catwalk when having something in my main hand make the item in the main hand "disappear"(only visually, opening another inventory or refreshing make the stuff appear again)
Trying to place an Iron Catwalk using Create Easy-Placement put the catwalk on top of one another, instead of side by side(or both, I can't remember right now)
