CleanOsu Fix

CleanOsu is a program most likely written by dukambe that replaces song backgrounds and deletes commonly unused map-specific skin elements. Due to an update to the osu! stable client, the original version of this program broke.

I decompiled the original exe with dnSpyEx and fixed a few things:

• Fix broken registry path
• Migrated from an old version of .NET framework to .NET 8.0
• Changed some code/added a package to make user.config work properly
• Changed obsolete form of MD5.Create()
• Add more elements to delete instead of replace image for (sliderendcircle, sliderstartcircle)

DISCLAIMER

TcNo-osu!cleaner is probably superior to CleanOsu, but I haven't tried it.
