[10115] Add function to update model_info at changes to scale or model.



* At every change to model or scale, the related data 

(bounding_radius/combat_reach) is now updated accordingly (note that player 

combat_reach are not changed like creature).

* UpdateModelData is called from within SetDisplayId while changes to scale has 

explicit call to UpdateModelData after new scale is set (mostly for aura scale)



* The updated values are calculated by 

(scale*bounding_radius)/(scale*combat_reach)

* Database values for bounding_radius/combat_reach are expected to be relative 

to scale like 1.0
