fixed nasty error with resizing 'fixed-start filesystems'. added a check

* include/GParted_Core.h,
  src/GParted_Core.cc: fixed nasty error with resizing 'fixed-start filesystems'.
* src/Partition.cc: added a check to prevent unused space from being bigger then total space.
* src/ntfs.cc: removed -Q from mkntfs. -Q bypassed some safetychecks to gain performance and (so i heard later) also had a
  tendency of failing ;) (Adrighem)
