Add a feature that show's members' last activities in build

I think an "activity log" will be really useful in this case, so you can fully decipher and depict which project member did what in case if you return to the project and someone wiped out a vast majority of the project. This thing has happened to me in the far past around January 2013, which I had 2 other members in the project and the player who actually did the damages totally tricked me! I ended up kicking the other member and then he later revealed that he was the culprit. I've also had other bad incidents like this which is why I've always preferred to build solo in KoGaMa since. I'm not sure if this idea would be possible at all, but personally I think it would really help a lot. But you can always build up trust over the years with other builders and form your own group or clan to do things in. But still, you never know if there could even be some "culprit" in one of those as well, so this idea would definitely help with a lot of things.
