Chain The Blocks

My first Vanilla+ mod [ :) ].  This mod introduces the chain block, it can be placed around most other blocks.  When shift-placed around blocks, they become blast-resistant, fire-resistant, hard to mine, un-interactable, and won't update. This block can be pushed onto other blocks by pistons or pulled off other blocks with sticky pistons, and it can have a dispenser place a block into it.  Mine a chain block with a silk-touch pick to get the chain block and contained item.  Crafted with 9 chains in the crafting table.
