Changeset 6348 for code/branches/presentation2

Message:

Adding OrxonoxClass::preDestroy(). This method gets called when an object is about to be destroyed. The only way to prevent that is by overriding preDestroy() and then creating a SmartPtr to 'this'. This allows us to delay the destruction of an object, for instance when destroyed by the loader.
