* include/Operation.h,
  src/Operation.h: minor (code) change in displaying errormessage. Made Apply_Resize_Move_Extended_To_Visual() a bit more
  readable (and thus debugable). This whole class could still use a soft, caring hand though :P
* src/Device.cc: Unallocate space < 1MB wasn't filtered out. fixed.
* src/Partition.cc (Set_Used): Unused wasn't set properly. fixed.
