Expected Behavior

If I place a machine next to a laser node, and then set allow input, or change the output direction, the LaserIO node should start inputing.

Actual Behavior

The laser node does nothing until receiving a block update.

Steps to Reproduce

1. Place a LaserIO node next to a tank or inventory.
2. Place an extraction card on the face next to the tank/inventory.
3. Place a corresponding insertion card on another face.
4. Place a machine against that face, so that the default output direction is towards the laser node.
5. Notice that nothing is getting inserted.
6. Place another block next to the laser node.
7. Notice that the things start getting inserted into the machine.

Additional Information

I think there should be a block update triggered when the capabilities presented by a machine on a given side change, e.g.

• output direction changed
• allow input toggled
• shutter placed/removed/toggled

I'm not sure if there are any other factors that would also change the capabilities provided.
