PraseTja: Add branches

- Needs the following changes to the database: change `easy`, `normal`, `hard`, and `oni` to `TEXT` type
- When adding songs to the database and if, for example, a song's 7-star difficulty has a branch, instead of `7` input `7 B`, this is to display song's branch support on the song selection
- Branch can be forced in debug
