Progress didn't work for several reasons:
- It was spinning when nothing was actually happening yet
(especially egregious with autodownload off)
- It was blocking exits (as all progress notifications do)
- When actually going to download, two progress notifications would
pertain to one thing
- It wasn't helping much with the actual implementation of score
re-import, cancelling the progress notification would result in
similarly jank UX of beatmap importing but not the score.
