AccessibleRelation

Peter,

In Java, if getAccessibleRelationSet() is called twice, are the relationships 
calculated both times?

It seems to me to be so from the code and would probably be necessary in the 
case of the MEMBER_OF relationship for a button as there is no guarantee that 
the members of the button group did not change in the interval between the two 
calls.

If the answer is yes, we will need to remove
  AtkRelationSet *relation_set;
from AtkObject.
