Johannes Schickel a2b96a2516 OPENGL: Replace SdlEventManager by SdlEventSource.
Formerly SdlEventManager was a subclass of DefaultEventManager but did not
really have anything in common with the idea of our EventManager interface.
Now I made a new object SdlEventSource which only subclasses EventSource
and which is responsible for obtaining events from SDL (and processing them).
