Changeset 11032 for code/branches/presentationHS15

Message:

fixed another situation where a timer may keep existing after the level was unloaded.
there is, however, yet another bug in this piece of code (marked with a TODO): a spaceship can be destroyed before the timer is executed which leads to a crash.
