* Added first working "display_as" type "duration".

* Changed Media:Length to int64, and use the new duration view in Tracker.
* Renamed the pretty name for video's Media:Length to "Runtime" (that's how it's
  called in IMDB, and I was never really fond of "Playing Time").
* FileTypes AttributeWindow needed to check the display-as types, as well as
  if the contents are acceptable when opening, too.
* Minor cleanup.
