Finished merging steampower into fluid mechanics

Steam Power is finally back with its other half basic pipes. Its been a
long time since these two mods were once the same exact mod. Now they
are rejoined though steam power was left rusting in the archive a bit
too long. Most of its content was remove and needs to be rewrote from
scratch. Fluid Mechanics aka basic pipes has since then become a nice
mod and is mostly bug free. Now with the addition of steampower maybe
just maybe now the mod will become more useful to the end user.
