Drop CONFIGURING file as it's unmaintained for at least a decade

Summary:
It still mentions dcop, so nobody updated it since the introduction of
dbus which is > 10 years. If nobody updates it and nobody complains that
it mentions dcop it means nobody reads it.

-1. Pre-configuring window-specific settings
-===========================================
-
-Window-specific settings is a feature of KWin that allows specifying some
-settings only for a specific window or windows. See the Window-specific
-settings section in the KWin configuration and the Special settings
-menu entries in Alt+F3/Advanced menu.
-
-One aspect of window-specific settings is the ability to specify various
-workarounds for (usually broken) applications that otherwise don't work
-properly with KWin. This section describes how to create additional
-window-specific settings that will be automatically used by all users
-without any need of manual configuration.
-
-Example case:
-
-Application FooBar does not specify any maximum size for its main window,
-but when resized to larger size than 1600x1200 it crashes because of a bug.
-Manual configuration of a window-specific setting that avoids this problem
-is opening and activating this window, selecting
-Alt+F3/Advanced/Special window settings, activating tab Workarounds, enabling
-setting Maximum size, changing it to Force and entering "1600,1200" as
-the maximum size, which will make KWin force this size as the maximum size.
-
-To create such window-specific setting automatically without a need of doing
-it manually for every user (for example when doing a large deployment), follow
-these steps:
-
-- Back up your $KDEHOME/share/config/kwinrulesrc ($KDEHOME usually being $HOME/.kde)
- and remove it
-- Run 'dcop kwin default reconfigure'
-- Create manually all window-specific settings that should be included (see above)
-- When done, check in Window-specific settings configuration module
- (Alt+F3/Configure window behavior/Window-specific settings) that all rules are
- included
-- Create a copy of $KDEHOME/share/config/kwinrulesrc and restore the original one
-- Rename the copy (i.e. the newly created kwinrulesrc) to have its unique name
- (e.g. foobar_fix_maxsize in this example case)
-- Be careful with manual modifications of the file, especially make sure the count=
- field in the [General] group is updated if needed
-- Create a file for kconfig_update like this (named kwin_foobar_fix_maxsize.upd
- in this example):
-
-# kwin_foobar_fix_maxsize.upd start # 
-Id=foobar_fix_maxsize
-File=kwinrules_update
-Group=Dummy
-Options=overwrite
-ScriptArguments=foobar_fix_maxsize
-Script=kwin_update_default_rules
-
-# kwin_foobar_fix_maxsize.upd end # 
-
-- The kconfig_file (kwin_foobar_fix_maxsize.upd) is to be placed
- in $KDEDIR/share/apps/kconf_update/
-- The file with the window-specific settings (foobar_fix_maxsize) is to be placed
- in $KDEDIR/share/apps/kwin/default_rules/
-
-
-All KDE user accounts should have these new window-specific settings added
-automatically during next KDE startup (or within few seconds if they are active).
-They can be checked again in the Window-specific settings configuration module of KWin.
