Pre-filter Pipes

[havvy]

TL;DR

Allow the player to choose which fluid a pipe accepts without placing next to a source/sink.

What ?

Pipes with fluids cannot mix with other pipes with fluids nowadays. When designing fluid networks, it would be nice if we could pre-choose which fluid the pipe network will allow before we place it next to something that is a source/sink so that we don't accidentally place it on a source or sink of a different fluid. This could be done via allowing right middle clicking the pipe and selecting the allowed fluid. If the pipe network already has one chosen, that same GUI can show which fluid is in it.

Why ?

It gives players another tool in planning their base and avoid shooting themselves in the foot.

This could be done via allowing right clicking the pipe and selecting the allowed fluid.

I believe a middle-click would be more appropriate, since middle-clicks are also used for setting inventory filters.

Right-clicking is already reserved for mining the pipe.
