#168 TAbZipper.OnArchiveItemProgress reports progress above 100% when zipping large files

[Rick Burgstaler]

If using TAbZipper.OnArchiveItemProgress() to monitor progress when zipping a file that is 3GB, the [progress : byte] member that is included in the event will report values greater than 100%.

I tracked the problem down to an integer overflow. I have posted my whack at the fix here:

Thanks,
