Changes: Add new class MWindowPropertyCache to further avoid round trips.

- Rename isTransitioning() -> hasTransitioningWindow()
- Rename thisIsTransitioning() -> isWindowTransitioning()
- Fix a crasher bug in windowctl
- Increase sleeps in two test scripts.
- Use MWindowPropertyCache to track window properties for windows that have
  received MapRequest
- Move hasAlpha() from MTexturePixmap to MWindowPropertyCache since it's
  dependent only to the X window visual
- Add beingMapped() to identify windows that have received MapRequest but
  not MapNotify yet
