Created on d8a23aad4 (just before skins were migrated to realm).
This contains:
- 2 beatmap sets (intro and disco prince)
- 1 score (set on disco prince using autopilot/DT)
- 1 skin (haxwell)
- 322 named files (from skin)
- 5 named files (from beatmaps)
- 270 total file infos
These share too much yet have very different constructor signatures and
property exposure. Just a clean-up pass as I begin to look at replay
submission.
At first I was planning on making `CompareTo` implemented at
`IRulesetInfo` itself and shared across classes, but turns out it only
implements it explicitly and not allow direct `IRulesetInfo.Equals`
calls.
It messed with my head enough that I decided to just let each class have
its own implementation and only allow same type.
