Added Diamond fluid Pipe

In response to #1210

How the pipe works:
It filters fluids just like the usual diamond pipe does. By placing a container with a fluid in the GUI you can determine which way the fluid will go. It has double the flow capacity of the golden fluid pipe (80mB/t).

It's not  finished pipe! It still requires more polishing. But since the idea might be rejected, I thought I could post it and see what you guys think, and if you like it, I'll finish the pipe and update the PR.
(Currently using diamond items pipe textures)

Repeat! This is not a final pipe. It requires more work. I don't have the intention to get it merged as it is!
