* src/Dialog_Base_Partition.cc,
src/Dialog_Partition_New.cc: Fixed 1 TB partition limit bug
- Fixed problem with spinbutton math that limited partition size
to a maximum just less than 1 TB.
New limit is just less than 1024 TB.
- Closes GParted bug #524948
* Makefile.am: Enhanced for new calling script gparted
- Added gparted script installation in sbin
- Added installdir parsing for gparted and gparted.desktop
