------------------------------------------+---------------------------------
 This patch series is an attempt at implementing the technical details
 (file size, file type, file date) info in the Journal details view as
 demonstrated in
 [http://wiki.sugarlabs.org/go/Design_Team/Designs/Journal#12 Eben's
 mockup] and thus #517 / #1033.

 Open questions (to the designers):
 a) what to do if mime_type is not set (currently: displays "Type: ")
 b) what to do if filesize is 0 (currently: displays "Size: 0B")

 I took the liberty of displaying the MIME type instead of the file
 extension because it's more appropriate IMO. File extensions are for
 legacy systems that need to store metadata in the filename and lose some
 of the information contained in the MIME type.
