Update app.json

Did some edits to lines 1-16. Will continue.
Portuguese Translation Fixes

Checked through lines 1-24:

- Fixed general verb and noun mistakes
- Fixed a few words that were still in English
- Kept role-playing game in English. RPG's should be understood by Portuguese-speakers. 
- Pretty sure como makes more sense than conforme.
- Believe I fixed some improper use of the imperative form. Correct me if I'm wrong.
- Pluralized recompensas
- Changed Bem vindo to boas-vindas. Bem-vindo may be accurate though?
- Other general fixes that escape me.

Plan to do more.
Update app.json

Skipped over lines 28-46 for now. Will come back to look over them.

- Line 56 - História makes more sense than Histórica I believe. Unless it's the history of a masculine object, such as histórico de crédito, história should be the go-to I believe.
- Line 4 - Originally put enquanto, switched to quando. Returned HP to pontos de vida. HP should make sense but might not to a Portuguese non-gamer.
- Line 60 - Changed from Logar-se / Inscrever-se to Iniciar sessão / Regista-se.
- Line 68 - Grupo to Partido
- Line 86 - Deletar to Eliminar
- Line 112 - Limpar (clean) to Eliminar
- A few other minor changes
