Separate logger and CLI

[PietroAmmaturo]

As of right now the CLI prints both debugging statments and game content, an easy solution for this is to remove the debugging statments, a better solution would be to create a "Logger" CLI along with a "Gaming" CLI (much like javafx works while debug statments are printed on the CLI)

Done, logger is now a class and a Client attribute, it logs to files in the client working directory.
