[MediaViewer](https://www.mediawiki.org/wiki/Multimedia/Media Viewer) displays the name of the uploader when someone is viewing the image, which turned out to be more confusing than useful. The task is to remove it.
The code that displays the uploader name is in mmv.ui.metadataPanel.js, but after removing it functionality in some other classes to fetch and store the data will become unnecessary and can also be removed.
By convention, existing files should not be modified significantly by reuploading, so we should show the first uploader (or do something more comples, like a list or a "more" link - but if we only show a single name, first uploader is more important information).
