HigherPower - Packet Switch

I ran into more Silverfish issues (Silverfissues if you will), so the Silverfish implanting machine is probably not going to work out.  For some reason, the cage blocks never take into account the posing metadata.  But I did start adding a new data processing machine, the Configurable Switch.  It will allow the player to choose which faces of a router-like block are inputs, outputs, or inert sides.  I don't want to use the tile entity to store the state of the faces, so I need to pack six two-bit numbers into the 16-bit metadata.  It's definitely possible, but I'm having a difficult time making it work.
