Optimize Network by not ticking on Session close.

- Rename render.render to render.effect
- Add isRunning to TickingElement since we can reuse our component
  classes...allows us to stop/start Network on demand (for instance).
- Printout feedback on Session terminations, stop network thread if we
  lose our session to not have needless CPU cycles wasted.
- Only iterate messages in Universe if networking is still active
