Quartz Fluid Pipe and Flow Rate Multiplier

Sorry for the delay on this - I had to attend to RL this week more than expected. Anyway, as the title notes, this is just the first two of several improvements for fluid pipes. It will be easier to merge this in now, then create a new fork with all the other changes that came in this week before I add in the valve Action since there would be several conflicts trying to merge it in if I add it to my current fork. Does that make sense?
