Qt5 handle theming-based change events
Qt generates three change events when changing the KDE theme:
FontChange, StyleChange and PaletteChange. LO has two:
SettingChanged and FontChanged. And like Qt LO will inform all
widgets / windows independently. To prevent several redraws,
this patch just collects all Qt's change events and notifies LO
once a bit later via a Timer.
