Add ascending sort option to date_based generic views

[noods]

It would be nice to have the ability to change the sort order of objects in date_based generic views. With the new addition of the allow_future option it makes sense to be able to sort by ascending date order instead of the default descending order.

For example in an event calendar you want to show upcoming events first.

I should clarify slightly, I'm talking about the archive_index view and changing the sort order of the "latest" objects.

After some thought I'm not sure this is necessary. I can just as easily just use an object_list generic view to get whichever objects I want in whatever order - the only thing I lose is the date_list context var, which would be easy to add if I want it.

Feel free to resolve.

Closing for the reason you pointed out in the previous comment.

Ignore my patch, intended to be an alternative - it doesn't work well with the other views.

My patch is fixed, so I'll describe it:

I have a site with many date-based views which share templates, and it just turned out that some needed to be ascending and some descending. The Django way would be to let me reverse the sort order, rather than make me rewrite some of them using generic list views.

My patch allows "-" in front of the date_field parameter to reverse the order. It also works with the other date_based views (not just archive), and sorts all the views by the date field as well.
