Feature parity with KDE 3.5 ++: minimized windows

Yesterday the itching became to bad an I hacked a bit on plasma and kwin to restore the workflow I enjoyed with KDE 3.5.

• The task applet in plasma can be configured to only show minimized windows since r874077.

And

• The "Present Windows" effect in kwin can now ignore minimized windows.(http://websvn.kde.org/?view=rev&revision=874292)
  

So now KDE support my OSX inspired desktop configuration again. I would include screenshots but plasma is currently broken. Such is the life on the bleeding edge.
