Update to 1.7.10

I really loved this mod in Tekkit, so I updated it from 1.6.4/BC 4.2.1 to 1.7.10/BC6.1.0.  I completely rewrote the network code, made the pipe output filters use the event system, changed the Adv. Wooden Pipe into a MjBattery, and added the missing GameRegistry.registerItem() call to createPipeSpecial so that teleport pipes worked, and removed all the stuff about Item ID's.  Lastly, I changed the build system to use forge's gradle scripts plus a cmd/bash script I wrote that copies the buildcraft source into the AdditionalPipes tree.  You'll have to manually delete the "assets/buildcraft" and "buildcraft/${everything except additional pipes}" folders from the outputted jar file though, or maybe that could be scripted.
