  Made scripttools disabled on Symbian by default, like on Windows.
  Got rid of "No such directory" warning when shadow building.
  Added qmake check for presence of RHttpDownloadMgr header
  Fixed crash on startup in Symbian debug build
  fixed hybrid heap Symbian udeb build issues
  qmediaplayer: show buffer status of 0%
  Progressive download in Phonon MMF backend: integrated with player
  Progressive download in Phonon MMF backend: added download managers
