Added crafting recipes for cracked, mossy, and carved stone brick

We used to be able to create these block types using a well-known glitch and there is a fair amount of them still in the game, but since it was patched there is no way to produce any more. These recipes allow us to craft them again, and provides a small application for 3 otherwise worthless items.

1 brick + 1 gravel -> 1 cracked
1 brick + 1 vine -> 1 mossy
1 brick + 1 flint -> 1 carved
