Engine: introduced deleteHelper() function

Browse Source 
The new deleteHelper() template function takes a pointer, saves it
to a temporary, sets the passed pointer to NULL and then deletes the
object it was referring to before. This way we can spot bugs caused by
undesired references to global objects at shutdown more easily.
