made 'deep-scan' optional in Read_Disk_Layout. Removed obsolete (already)

* include/Device.h,
  src/Device.cc: made 'deep-scan' optional in Read_Disk_Layout. Removed obsolete (already) commented function.
* include/Partition.h,
  src/Partition.cc: Took used sectors out of Set() and added a Set_Used() function instead. Also added Reset() .
* src/Dialog_Partition_New.cc: minor change to make use of the new Set() in Partition..
* include/Win_GParted.h,
  src/Win_GParted.cc: show pulsing progressbar while refreshing devices.
