(un)Manage Docks based on WINDOW_TYPE

Hi,

this is a replacement for the example code in Config.hs that should detect
and unamange, for example, the gnome-panel.

The problem with that code is that it also unamangs dialog boxes from gnome-panel
which then are not usable (no keyboard intput, at least here).

Greetings,
Joachim
