Enum ordering support

[phpfui]

I would love to get an ordered_enum_elements like ordered_class_elements fixer.

I would think the options would be 'false' (don't order, leave alone even if ordered_class_elements is set) or sort_algorithm = name or value.

My use case is this:

enum IncludeMembership : int
{
	case NO = 0;
	case NEW_MEMBERS_ONLY = 1;
	case EXTEND_MEMBERSHIP = 2;
	case RENEW_MEMBERSHIP = 3;
}

I would order it by value, but I can see a use case to order by name, or don't order at all. Currently it defaults to order_class_elements, but I use enums in the user interface, so the order makes a difference to me.

I would be happy to submit a PR, but would like some guidance as to what this should be called, the options and also where to implement this.

Thanks for the help.
