- All of the slab logic has been rewritten.  It is no longer being double registered and has moved away from the depreciated GameRegistry methods that were being used.  This fixes the “broken slab” variant that would crash a client upon placement.  When updated a world with my slabs in it, it will say it cannot find all of my slabs and ask if you want to continue.  Do not fear, it is just getting rid of the unnecessary broken “ghost” slab. All working slabs are not affected by this update.

- The Paper, Sugar Cane, and Leather storage blocks now have a new recipe.  It is basically the same one, except for a blank space in the middle, like how chests/furnaces are made.  In case my mod is still in conflict with another mod like Quark, there is an option to just disable the recipe for my storage blocks. You can still get the storage blocks from creative regardless.
