Update Italian (it-it) translation

[Kappa971]

I would like to point out:
In PROGRAM_IMGMOUNT_HELP_LONG:

  [color=cyan]BOOTIMAGE[reset] is a bootable disk image with specified -size GEOMETRY:
            bytes-per-sector,sectors-per-head,heads,cylinders

And in PROGRAM_IMGMOUNT_SPECIFY_GEOMETRY:

bytes_per_sector, sectors_per_cylinder, heads_per_cylinder, cylinder_count.

Shouldn't they be indicated the same way?

Yes, they are both text / documentation, so should use the same notation; I've pushed a fixed for that.

Also here:
[color=blue]IMGMOUNT drive-letter location-of-image -size bps,spc,hpc,cyl[reset]

@Kappa971 , can you fix the conflicts? (The 'Resolve conflicts' button below will give you a web editor to update the lines)
