Pipewalker OIL STRIKE theme (0.9.3 or newer)

This tileset is a variant of the Plumbing tileset included in Pipewalker. Instead of water being sent to taps, we have a refinery waiting for oil catchments to be found, and pipelines built from these strikes. Connect the oil wells (shown as a drop of oil) to the refinery.
