accessing struct as struct array rearranges field order

[Willem Atsma]

Not urgent in any way, but it has broken some of my code. 

When I create a structure with a specific order they are rearranged
depending on how I access them.


	D = struct("c",1,"b",5)
	fieldnames(D)		% returns correct order
	fieldnames(D(1))		% returns fields in alphabetical order

I assume orderfields is called somewhere when using subreferences.
