--instead of reading the kwin values all the time

only on startup and when the kwinrc file was
updated/changed
BUG:411657
FIXED-IN:0.9.3
--when the user uses Meta+A to cycle between the Views
configuration windows then in such case when NO Config
window is shown the LAST ONE USED should be shown again.
IF a Config View is already shown then the NEXT should
be shown afterwards
--no reason to load Mutiple layouts linked file
as a Pseudo Central layout. This way no needed
checks can be removed and things are still working
as before.
