Title: Liquid in tanks should diffuse sideways. - tanks next to each other act as 1 tank.

over several ticks liquid will spread out between adjacent tanks - diffusion is over-damped (moving 1/5 of the difference per tick) so no oscillations can occur.

If a tank is nearly empty, and the adjacent tank has 0, then all liquid will move to it. (this scenario happens when liquid is being drained out from 1 point)

This patch should be good for either master or 131 branch. I'm placing it in master, because the back-port to people using 1.2.5 still would be nice.
