Display owners next to map authors on map page

[HSZemi]

Map info currently looks like this: After this change, it would look similar to this:

This allows users to more accurately judge the quality of uploads: Is the map owner the original author, a tournament host, or just a random dude on the internet?

This means that usernames would appear publicly on the site for the first time.

• discloses who (supposedly) uses the site
• could be used for attacking those accounts (but why?)

This change is scheduled to be implemented not before 2019-10-01.

I am going to email all users about this change and its implications soon™ on 2019-09-15 and ask them if they have reservations against it. If points are brought up that speak against this change, it can also be canceled. If a user's concerns can be resolved by other means while still implementing this change, I will also be willing to do so.

The change is live now :slightly_smiling_face:
