Add a central user message extraction for all KWin client.
(The config programs have already their own .pot files)
CCMAIL:kde-i18n-doc@kde.org
(Note: there is currently not much of a choice to add a new .pot file,
as KWin has already many of them and we are in message freeze.
But at least this new .pot file can be shared between all clients, which
share most of the user visible strings.)
