Order Received sorting

[John Abd-El-Malek]

After the recent performance gain (which is great, thanks a lot), one of 
my favourite things suddenly disappeared.  This is feature where we can 
sort a folder by the order received.

This was really great, because everyone has different times in their 
computer and as a result if there's lots of messages coming in closely 
then the order is messed up.  Can someone please bring this back?
