Maschell 05aea5756b Various improvements including:
- Display name/type of the partition
- Block home menu when launching via HBL
- Use libmocha instead of libiosuhax, which should result in a small performance boost
- Improve logging
- Improve memory management
- Add option to abort dumps
- Slightly improve .wux handling
