KnightCraft blocks and stuff

This mod has things made for the KnightCraft server, you are welcome to use it for your own modpacks, but do not ask for version change as I will not do that.

Features:
~ Three tiers of crates for obtaining enchants
~ Gold and silver coins
~ A Siege Block, intended to replace obsidian for sieges, gives warnings on starting to break and on full break
~ Gravel and Bricks, a block with good blast resistance but can fall like sand, intented to serve as a stop for battering rams against walls
