Added Thaumium Pipe

You'll need to add BuildCraft to the build path in order for this to work.

The pipe triggers don't work on build craft versions bellow 4.2.0. Gates before that didn't take NBT into consideration. I had to get a PM in in order for this to work. It won't crash, it will only not filter the essentia.

I probably did stuff in ways you don't like, feel free to tell me what you want changing and I'll adapt the PR.
(or if you want you can change whatever you want yourself)
