Kill window without focusing it first
Kill window without focusing it first

This patch requires the patch "add killWindow function" in xmonad.
Before this patch, people would experience “workspace flicker” when closing
a window via EWMH that is not on the current workspace, for example when
quitting pidgin via the panel icon.
