This patch introduces a new class for managing the cinema overlay (two black bars) and cutscene mode. This makes it more extensible for the future, e.g. allowing to display text on the bars. Since <include> elements can only be placed inside an <object>, this patch needs to restructure session.xml a bit and also adds some explanation comments while at it.
