Add column: last repo update

[d9k]

Add column: last repo update. Probably add script to automate column change. Execute this script every week (at first manually then by cron, with auto-push).

That is something I had in the back of my mind, but too many columns would start to kill readability of the table. I think it is now in a good balance. What I was thinking instead was to use JSON to generate an HTML that would be hosted here on GH that would allow to perform columns picking and some filtering and could contain much more information. But didn't have a time to proceed with that idea.
