FileManager: Show directory size and file count in PropertiesWindow

Browse source 
When displaying properties for a directory, the PropertiesWindow now
shows: the total number of files, the total number of subdirectories,
and the total size of all files, in bytes.

These numbers are calculated on a background thread, and current
progress is displayed to the user every 100ms.
