Subject: [PATCH] [kwin/kcmdeco] Show an information if close window by dbl
 click gets activated

The option changes the behavior of the menu button, thus we should point
out to the user that the behavior changes.

This is only done for Auroae configurations as other decorations have to
take care about it themselves.
