Alias *older aj*-type shorthands into *older applejack*-type Mane Six tags

older aj -> older applejack  
older ry -> older rarity  
older ts -> older twilight  
older pp -> older pinkie pie  
older rd -> older rainbow dash  
older fs -> older fluttershy

I wouldn’t call an eight character alias “short-hand”.
 
I agree with the idea, but those need about at least four fewer characters before they’re worth anything.
