Fixed crashes when importing beatmaps (due to more async issues).

Don't call MusicController.loopTrackIfEnded() if a beatmap reloading thread is running.

Other changes:
- Fixed issue where long download result text would be drawn outside the result area by adding a clip.
- Changed default music offset from -150ms to -75ms.
