GetAllChildObjects (object)
Returns an objectlist containing all objects directly or indirectly contained by the parent object (i.e. including all children of children etc.)
For example, if object A contains object B, and object B contains object C, then GetAllChildObjects(A) returns a list containing B and C.
Use GetDirectChildren instead if you only want children directly contained (in the above example, only B).
NOTE: This a hard-coded function.
