boot info script 0.45

Version 0,45 of the boot info script was released.

Changes:

1. The scripts now checks whether all required programs are installed.

2. Fixed a bug which prevents the boot information to be displayed if non MS-Dos partition table is present, but not in use.

3. Fixed a bug which caused the size of md-raid partitions to be computed in blocks rather than sectors.

4. Results.txt now displays a warning if an extended partition links to another extended partitions. (In such a case, gparted will show the whole hard drive as unallocated and fdisk gives an "omitted empty partition" warning)
