It's as the title says, this is a port of Pfaeff's Mod for 1.7. For obvious reasons the Chest Trap was removed. You can find all the info about this mod in the original thread. linked previously.
I tested this but not super thoroughly, so if you find any issues give me a poke.
If you have any problems with the mod or just want to contact me, you can find me on Twitter (@Vazkii) or IRC (#vazkii on irc.esper.net).
