Subject: [PATCH] - Fixed: When loading FBehavior::SerializeVarSet() would only
 zero the variables if there were   non-zero variables to load. This was fine
 when all variables defaulted to zero, but map variables   have been able to
 default to something else for some time now. This meant that if all map  
 variables were zero when the game was saved, they would be restored to their
 default values   when the game was loaded.
