Teleporters and Sensors (0.18.1 Alpha)

This update adds teleporters and wired sensors  that detect the presence of Actors.

Wiring a teleporter is very similar to  the pump, but transports Actors instead of fluid.  It has one input and one output.  When the input gets a true signal, it detects the Actors that are in a 3x3 square above it and transports them to a random teleporter linked to it's output node.

Here's a demo of these new features as an animated gif:
