WordCamp Sessions: Default sort order for Manage Sessions should be "Time"

[danielbachhuber]

Because Sessions are closely tied to a schedule, the default sort order in the Manage Sessions view should be whatever post meta field is associated with "Time". ASC would work just fine.

I uploaded a patch that causes the Sessions to be listed by date in the admin panel.

This is the patch to apply!

Sorry--after I submitted the first patch, I found that someone already had start to implement this, so I used their function, and modified the logic a bit so that the default (blank) 'orderby' is set to ascend the time field.

This looks good, thanks Jonathan :)

A few small tweaks I'd suggest:

1. Add the date to the Time column, because when there are sessions from multiple days it can be confusing to see the times appear to be out of order.
2. Rename the column to Session Date / Time because it now includes the date, but we don't want it confused with the post's Date column. Another idea would be to just remove the Core Date column, since it's not that useful in this situation.
3. There are a few ​coding standards issues around whitespace usage.

A good follow-up patch would be to remove the old "voodoo" workaround because ​wordpress:#23268 is fixed now.
