fixed some issues with pipes but the main change is the addition of the
extractor valve(better name to come). This valve cause a machine to
start to output liqiud to basic Utilities pipes at a pressure so they
work. The Valve can also be turned off by redstone input to act as a
output control of storage tanks.
I've made a mess of changes since last upload. Main big change is change
in forge file formate that merged minecraft and common folder. The other
is the complete rewrite to Forge Liquid api. So far only the pump,
boiler, and pipe are converted to the new system. The pipe will actual
not fully work with most machines since it can't drain liquids out of
machines. In future update there will be a block to do this called a
pipe pump. Other than those changes nothing much is diffrent.
