CodeCraft

Removed FTBUtilities (and FTBLib) since MyTown2 worked so perfectly. Also, it does not need to be installed on clients so voted against including it in this pack. In addition, I added the Tinkers' Mechworks since the drawbridge is so super awesome and cool, as well as runic dungeons to get some more indestructable blocks for when I create testing spaces where the children can use their blocks to program turtles.
