[Expo] handle Escape key on press, not on release

Handling the Escape key on release causes problem with Expo intercepting Escape when pressed (and released) in a modal dialog.
[Window Manager] make sure mixing effects for minimizing and mapping work together

In particular, make sure that the combination of desktop-effects-minimize-effect 'fade'
and desktop-effects-map-effect 'none' does not leave the restored window invisible.

This also takes care of the case where desktop effects are temporarily turned off when
restoring a minimized window, which could leave the restored window in a bad state.
[Alt-Tab] use Main.isInteresting to filter out windows to show in Alt-Tab

The skip-taskbar flag is not applicable to Alt-Tab but to the Task Bar.
