Lift requirement that sinks terminate a signal chain.

These changes make it so that sinks can be placed in the middle of a signal chain, similar to how filters currently behave. Other changes include:
- Simplified logic for drawing GraphView
- New aesthetics for GraphView
- Fixed bugs when moving around Splitters or Mergers
- Add a threshold for dragging editors, to avoid accidentally triggering a "MOVE" event
