Allow filtering by gamemode on the beatmap history page

[Lyti4n]

https://osu.ppy.sh/beatmapsets/events?user=&min_date=&max_date= there is no way to filter by mode on this page for some reason i think it would make the page much more useful. As an example I wanted to look at a list of recent disqualifications but there was no way to tell what gamemode they were in without clicking on each individual one.
