Martin Gräßlin 23f2de009b Effects can provide support information through properties
The supportInformation is extended to also read the properties
on all effects. In addition each effect can be queried just for
itself through D-Bus, e.g.:
qdbus org.kde.kwin /KWin supportInformationForEffect kwin4_effect_blur

All effects are extended to provide their configured and read
settings through properties. In some cases also important
runtime information is exposed.
