Theme: Use QVariantMap for theme properties

Browse Source 
QML can directly mirror this into a JavaScript object, so there is no
need to manually copy the values into a different container. Also,
QQmlPropertyMap is very expensive as it will listen to changes to any
value in the map. We never use this. It would be entirely enough to
update the whole map at once if we ever want to update the theme at
runtime.
