Map appears as "Not submitted" when beatmap creator changes name

[cobss]

When a beatmap creator changes their username, local files do not reflect this change, causing leaderboards to not load. For example, the case with Wanko/Levi

This will also cause a "The beatmap you're trying to submit isn't yours!" error because the local files do not update when someone changes their username.

Workaround is to simply re-download the map and/or manually change the creator as a .txt file
Though I would suggest using user IDs for listing the beatmap creator and .getUsername(int:userID) as a preventative measure

the case with non-submitted status appearing is not caused by the client; statuses are fetched from osu-web-10, which i don't have access to. cc @peppy maybe you can provide input on this one.

using user ids for beatmap creator would mean the .osu file format would require a breaking change. this is out of scope.
