ungrouped sorting on date

[simoncn]

Unfortunately, I can't think of an easy fix other than your suggestion to populate the empty Comment tags with an older date.

I think the correct fix is for me to change MinimServer so that empty tags are always sorted at the end of the list, even when the - prefix is used to reverse the sort order. This won't happen any time soon because I am about to go travelling for 5 weeks.
