Included:
-The process lists use |= instead of += due to the increased stability of the former against double additions.
-Atmospherics machinery is moved under the pipenet processing.
-Modified the atmospherics processes to return 1 when theyve done something, and 0 if they aint done jack shit. Then called scheck() if they return 1, possibly reducing unnecessary scheck calls while still managing to smooth out the atmospherics processing.
-If a powernet happens to get rebuilt by either powernets or power machinery scheck() is also called
Tanks are now unaries, not pipes.
Portable connectors are now unaries, not their own type.
Valves are now binaries, T-Valves are now trinaries.
Pipes as much as possible now use the general attackby code.
Slight changes to pooling code.
Removed loads of duplicate code that existed for no real reason.
T-Valves now come in manual and digital and mirrored under those types, not the other way around.
Mirrored connecting sprites for T-Valves should show up properly now.
Never again.
