Subject: [PATCH] Bug fix #75: --invert-color-include not working & others

- Fix a small bug that breaks --invert-color-include if no other
  blacklists are present. Thanks to MaskRay and xiaq for reporting.

- Disable --unredir-if-possible for multi-screen setups.

- Fix a bug that causes --no-fading-openclose to have no effect in some
  cases. Add w->in_openclose to keep track of window open/close state.
