I'll have to update all my scripts... but its ok if somebody wants to 
make this change (with index in 1,...,6 please).

1/ Many users around are using sigma1,2,3 at the moment. More accessors 
can be added but not sigma's removed.
2/ sigma1,2,3 are not averaged stresses but _prescribed_ stresses
3/ For actual stresses (the tuple above), average them in python if you 
need, I see no reason to give access to 3 values only when there are 6.
