Title: Comet bug fix + Improve handling of non-cached comet actors

- Make lastRenderTime, delta timestamps, and lastListenerTime
consistent with each other as they are directly compared
- Add alwaysReRenderOnPageLoad as alternative to devMode
- Try to reduce number of renders for non-cached actors
