the idea being to not write anything into the Katie config and possibly
even drop support for overriding Katie settings from config.
on a side note font and palette settings are wrapped via classes
(KGlobalSettings and KColorScheme) and hard-wired to configs rather than
being a runtime thing (e.g. getting the font to use for menus via
QApplication::font("QMenu") instead of KGlobalSettings::menuFont()) so lots
to do on that, as for how it will benefit Katana and Katie - less config
parsing possibly, QPalette objects are shared data for example

fixes some race-conditions, for reference:

also the exit() call in case of failure to open the temporary file would
exit the program calling runRdb() (systemsettings for example) with
status 0 (normal, when an error ocurred), that is no longer the case
