Send destroy events for minimized, attached windows to Cinnamon, so the
parent un-dimming can occur.
Add "osx" click-to-focus mode.

- Requires cinnamon-desktop wm schema update.
- Clicking on a window focuses and raises it, but does not
  pass the button click event to the window.

Extra notes, questions:
- Haven't tested thoroughly...
- testing, more testing...
- enable mode by:
     gsettings set org.cinnamon.desktop.wm.preferences focus-mode 'osx'
- escape it via cinnamon settings
- still needs cinnamon patch for settings
osx-mode: Handle programs like multi-window gimp in the same way
as click-to-focus mode, but only within the gimp toolbox and image
windows.  When switching between multiple image windows, osx focus
behavior is preserved
