Subject: [PATCH 05/12] Manually keep track of jobs sources

DataSources source is a QStringList property which means changes within cannot be tracked
causing all the job delegates to be destroyed and re-created when sourcesChanged is emitted.
This is pretty wasteful and also causes the delegates to lose their state (eg. details expanded)
