offline_items_collection : Added helper class to determine progress

Added a struct in OfflineItem to contain the current progress value,
max value and progress unit. The progress unit can be bytes, files or
percent. The information should be set in native and subsequently it is
passed to java where various types of messages such as "x files left"
or "x seconds left" is shown in the notifications and download home.
