Implemented playing a movie on doubleclick

Movie files are played in the default player when double clicking on a
movie, but not when doubleclicking on a series. The latter invokes the
edit event on the series. Don't yet know if this is a good thing or not.

Changes on the way there:
1. new helper function for finding the right player. Still need to fix
FileSystemWidget to also use the Helper::function. It's a simple copy &
paste from there.
2. added function SeriesTreeModel::findSortedMovies. It returns a
QFileInfoList sorted by seriespart and fileno.
