xmonad: add takeTopFocus logHook This is required to make IntelliJ (and supposedly all other Swing applications) properly notice that they've recieved the focus. According to [0], the problem is that "xmonad does not follow ICCCM and ignores WM_TAKE_FOCUS protocol", but the patches on that ticket haven't yet been accepted, so the function was added to xmonad-contrib as a workaround until something happens in xmonad proper.

# This is broken into its own file on account of not being able to
# properly make opendiff-w bail when opendiff is unavailable.
