* src/Device.cc: when the libary of an optional filesystem (atm only reiserfs) wasn't installed, every scan printed an error
in the console (df couldn't find the partition listed). Fixed by checking if partition is busy before using df.
* 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.
* 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.
