[patch] Additional sorting for posts with the same date

[GoogleCodeExporter]

This problem should be especially obvious after the first feeds' update
either if posts have "dynamic" timestamps (generated along with the feed)
or don't include these at all, or if the posts' ordering is set to "Date
fetched".

Feed "channels" will get mixed randomly since most posts' should contain
exactly same timestamps and there's no ordering criteria past "date_modified".
If updater is run with the long-enough intervals and works pretty fast, the
problem should persist after the initial update.

As a solution, I've added extra "feed" criteria past "date_modified", so
the posts from the different feeds but with the same date won't get mixed
like that.
