Improved X11 focus event filtering.

Browse Source 
Some focus events need to be ignored to allow functionality like
Alt+Tab and volume indicators to not affect application-visible window
focus.  However, the previous filtering was too broad and missed virtual
desktop switching, Alt+Tab and programmatic iconification.

Fixes #405.
