Sorting aliases

@mkly linked here from a forum thread and because there was no order I couldn't find what I wanted. So I have sorted the aliases. I have no idea if there is code anywhere else that is dependant on sequence and hence vulnerable to side effects.

I thought about sorting other arrays, but maybe an alpha sort was less helpful in other cases, so left others alone.
