* Implemented that pressing the window modifier plus double click will minimize

the window. This closes ticket #6429.
* Got rid of useless _Extract*() methods. Also removed the _ActionFor() variant
  that only took a message.
* Removed unused "invalidate" variable in MouseUp().
* Coding style cleanup.
