Build a logic circuit

[gk646]

This is one of the proof of conecept goals i wanna be able to make with this editor.

This task includes the following:

• Create new logic components, maybe a bit adder
• Usage of the boolean type to simlute ON/OFF states.
• A clock component that sends out On signals on a configurable frequency
• A "teleporter" node so you can build circular graphs - up until now its only left-to right (if you dont want it to look ugly...)
