Sort options

Whenever we sit down to watch a movie, my wife says "it's late so pick a short one". It would be great to be able to sort by runtime, at least.

Generally, sort options for several metadata items could be useful: running time, name, resolution, rating, release date, date added.

Sorting would of course be inependent of filtering and available in most or all views. Some mechanism to reverse the sort order would be great as well, such as selecting the current sort key again.
