ODBV improvements

Thanks to suggestions made by Frits Hoogland, I made some improvements to the ODBV. The new version can be found here: http://ora-600.pl/oinstall/odbv.x86_64

The changes are:

• Recognition of first, second and third level bitmap block
• Recognition of pagetable segment header
• Block number ranges on the left side

The blocks will be coloured properly to belonging segment.

Here you can find a sample output:

Have fun! 🙂
