[aurorae] Share QQmlEngine in configuration mode
Review Request #123728 - Created May 12, 2015 and discarded
Currently the decoration kcm list creates a new QQmlEngine for each of the previews. This patch introduces a way to pass the root QQmlEngine to each of the instantiated plugins and allows them to use it instead of creating a new QQmlEngine. The hope is that this change reduces the risk of crashes and also makes loading the list faster and to use less memory.
