Have date of iso build in download

[santosh]

Agree, and I posted about this too… not having a build number corrupted my multi-day download of Bluefin ISO, or I believe that was the culprit.

Unusual ISO issue

Following up on this issue I posted above, a suggestion could be to add a build/version number suffix to the ISO download URLs pushed to the website. This will prevent people who pause and resume downloads (like I did above) from downloading bytes from successively updated ISOs and stitching them together into an invalid ISO file.
