[MERGED PR] Scaling pipe leakage

[Splints]

As far as I know, the pipeburn is the only current way to get a million credits in one round. If I am reading things right, this seems like it might kill that. Will there still be a method to hit exponential growth and make the million objective? There are also a lot of cool things that are only possible at really powerful burns like the gibbing PTL. I would hope there would still be ways experienced CE's and engineers could hit those numbers. It's not just the objective, if exponential growth becomes infeasible there is little incentive to go beyond a standard char burn. The power requirements to make a good amount of money are just too high without exponential growth IMO.

I do like the new sprites though.
