Devlog #32: New component: CLOCK (finally)

This one was relatively easy to implement! The tick system was already there, but it was only triggered by user interactions. Now, your circuits run at 10 ticks/s, and the clock has a constant 1 Hz square signal (the recording below is choppy, but yes it is indeed a 1 Hz periodic signal)

This component only has one output. I thought it would make building complex circuits easier if the other sides were isolated.

Next steps: 1-bit memory, and then a lot of UX/UI improvements!
