Add option to make a copy of the game folder before patching (console arcs, but also generally)

For all games, it would be nice to make a backup of the game, in case the installation fails, or just so the user can play either copy.

The user can do this manually, but adding a simple "make a copy of the game folder" option should be reasonably easy

If a user wants to restore their original version (to re-patch or otherwise), they need to manually delete the game and then re-download, then re-install it.

This is especially important for the Console arcs, which share chapter 4.

We should remember to remind users that steam sync won't work on the duplicate copy/steam won't launch the duplicate copy, and any other gotchas with the other copy.

Analise o script principal do patcher para entender como ele localiza e modifica as pastas do jogo. Identifique onde a operação de cópia deve ocorrer antes do início da aplicação do patch. Verifique as operações de arquivo existentes e o tratamento de erros para integrar a lógica de backup. Teste aplicando um patch a um jogo para garantir que a cópia seja criada e o original permaneça intacto.
