Show picture size or duration in FilesTreeView

Finally managed to view size of pictures or duration for movies in the
file view. That values are not held in the database, they're created on
the fly. For this to perform I created a disk based cache.

I also had to create some convenience functions:
FilesTreeModel::streamInfo(const QString &)
FilesTreeModel::pictureInfo(const QString &)

The cache is a QDataStream and will be deleted if the magic doesn't fit.
