[openbox] Support for _NET_DESKTOP_LAYOUT property, i.e. config_desktops_rows option, request

[Ilya Tumaykin]

Hello.

I've been using Openbox for a long time together with various panels and 
pagers. Now I'm trying to get KDE/Openbox tandem work as neatly as plain 
Openbox. And it works fine in most aspects.

However, one of the missing functionality pieces of the said tandem is the 
correct number of rows in pager, i.e. correct _NET_DESKTOP_LAYOUT property 
setup. I've read EWMH spec and aware that this property should be set by 
pager, not WM. Unfortunately, KDE does not follow standard in this case and 
use KWin to set this property since 4.8.0 (see 
https://bugs.kde.org/show_bug.cgi?id=277965#c7).

After some googling I've found a patch, which adds this functionality to 
Openbox. It was mentioned in 2004 and 2005 in Openbox ML: 
http://icculus.org/pipermail/openbox/2004-June/002624.html and 
http://icculus.org/pipermail/openbox/2005-September/003667.html.

In these mails this patch is considered unfinished/unstable. I would like to 
know if this patch (possibly an updated verision) could be included in Openbox 
now? Otherwise KDE/Openbox tandem is broken. Maybe I could help to 
improve/test this patch in some way? I am not Xlib programmer, but I will try 
to do my best, if you give me some hints on what needs to be done.
