[openbox] ToggleShowDesktop exclutions

[Alexey Korop]

Hi, All

   For some reason I use Conky windows in "own_window_type normal" mode.
In this case ToggleShowDesktop operation switch Conky windows
visibility, which is undesirable.
   Is there a way to leave the Concy windows visible despite their
"normal" mode?
   Perhaps it would be wiser not to toggle the visibility of windows
with hints "undecorated,below,skip_taskbar,skip_pager"?
