First load gui and then scan devices, this resulted in way faster startup 

* include/Win_GParted.h,
  src/Win_GParted.cc: First load gui and then scan devices, this resulted in way faster startup and is more satisfactory (imho)
  Also did some minor code cleanups and rearranged some functions needed for applying operations.
* src/Dialog_Progress.cc: few minor code cleanups.
