Update microblocks.cfg

I thought it would be a good idea to add the micro-block for Chisel Blocks and the crafting table, mainly for aesthetic purpose. As I was designing my house, I went to use build something and realized these blocks were not in micro-block form. I find chisel blocks to be great for making things look nice and if you are able to use multiple blocks within the same block area, it can create some good effects for design.

Note: I did not do micro-blocks for chisel iron bars, glass panes, stairs, slabs, or floor carpets
